	Abstract:The porous carbons derived from naturally abundant bamboo shoot shell for the application of supercapacitor are further activated by chemical activation with ZnCl2, H3PO4 and K2CO3. The influences of activation condition on the pore structure and physicochemical properties of the as-prepared porous carbon samples are investigated by scanning electron microscopy (SEM), transmission electron microscope (TEM), nitrogen adsorption-desorption isotherm, cyclic voltammogram (CV), galvanostatic charge-discharge (GCD) test, electrochemical impedance spectroscopy (EIS) and cycle life measurement. The results show that the porous activated carbon prepared at 1:1 weight ratio of K2CO3 to bamboo shoot shell exhibits a specific surface area of 1800 m2 g-1 with the average pore size of 3.35 nm (AC-K2CO3-900). In addition, the AC-K2CO3-900 shows a high specific capacitance of 287 F g-1 at the current density of 1 A g-1. Moreover, the AC-K2CO3-900 supercapacitor holds high capacitance retention of 95.80% even after 10000 cycles, indicating its potential prospect for the application of high-performance supercapacitors.

	Abstract:To explore a method with high activity and selectivity,is the key to improve Fischer-Tropsch synthesis(FTS) technology and the main focus in academic field. Herein,a photocatalytic route was employed into traditional thermochemical FTS,constituting a photothermocatalytic system.The 20%Co/TiO2 nanotube catalyst was prepared by the incipient wetness impregnation method, and applied to phtothermocatalytic process to investigate the role of illumination for the FTS reaction.The introduction of light dramatically improved CO conversion, from 9.18% to 63.92%.In addition,illumination gave rise to an increase in light paraffin selectivity.The present work demonstrates that photothermocatalysis could be a promising research direction on enhancing FTS catalytic performance and adjusting product distribution .

	Abstract:Newborn two-dimensional materials (NB2DMs) beyond graphene such as transition metal dichalcogenides (TMDs) exhibited excellent optoelectronic and mechanical properties as well as high theoretical specific capacity, which make them become the promising building blocks of flexible energy devices related to energy conversion and storage. Compared to graphene with zero band gap or traditional friable materials such as Si, these NB2DMs are more suitable to construct flexible devices as active layers of optoelectronic devices or as active materials for batteries. The presented review focuses on the recent advances in bendable energy devices based on NB2DMs, including batteries, supercapacitors (SCs), solar cells, photodetectors and nanoerators (NGs). The NB2DMs pave a new way to construct next-generation flexible energy devices with improved performance and we believe that those devices will be seen in our daily life and change our lifestyle in the immediate future.

	Abstract:In this paper,This study reports a sensitive electro-analytical method for the determination of trace amounts of Cu2+ using a phytate functionalizedpolypyrrole nanocomposites modified glass carbon electrode.The phytic acid-polypyrrole (PA/PPy) nanocomposites were prepared by an electrostatic adsorption and ultrasonic mixing. The results showed that bothPPy and PA/PPy modi?ed glassy carbon electrodes have electrochemical responses towardCu2+.However, owing to the synergistic contribution betweenthe PPy and PA, the PA/PPymodi?edelectrode exhibited higher sensitivity than that of PPy modi?ed electrode.The PA/PPynanocomposites functionalized electrodes showed a good linear relationship with Cu2+ at concentration ranges of 10-60 μg L-1, andthe limit of detection(S/N = 3)was 1 μg L-1.In addition, the electrochemical sensor was appliedtoassay Cu2+in real water samples.

	Abstract:Reviews: A step-by-step theoretical protocol based on the density functional theory (DFT) and time-dependent DFT (TD-DFT) have been performed to study a Ruthenium polypyridyl complexes named N3 sensitized TiO2 solar cell including dye excitations and electron injection. Hybrid DFT XC functional B3LYP and PBE0, and recently proposed long-range corrected XC functional Cam-B3LYP have been applied, which provide reliable interfacial distances and interaction energies, and predict a significant excited-state charge transfer from the donor to the acceptor. Our study reveals three binding structures of the sensitizer anchored on a TiO2 surface. For the different anchoring modes, the possibility of a favorable electron transfer from the excited dye to the semiconductor conduction band (CB) are suggested. The three possible pathways are from the different parts of the excited dye to nanoparticle (TiO2){38}, resulting in the different timescale of the electron injections.

	Abstract:Dendritic NiCu nanopearl chains in 1:1 atom ratio were galvanostatically deposited on a Cu substrate for catalyzing hydrogen evolution reaction (HER) in H2SO4 electrolytes. The morphology and composition of the deposits were characterized by FE-SEM/EDX analysis. All the four-level branches of the dendritic nanoalloy grow in a pearl chain structure of nanoparticles with a diameter of ca. 50-80 nm. The electrocatalytic activity to HER was studied by linear polarization and chronopotentiometry. At the NiCu nanoalloy electrode, the exchange current density of HER was 2836 times higher than at Cu electrode, while the overpotential at a current density of 50 mA cm-2 was decreased by 265 mV. The NiCu nanoalloy can not only significantly reduce the charge transfer resistance of HER, but also facilitate the elimination of the generated hydrogen from the active sites. This work indicates that the dendritic NiCu nanochains may be a potent candidate as a non-noble metal catalyst for hydrogen energy production.

	Abstract:This study investigates catalytic adsorptive desulfurization (CADS) of model diesel fuel using TiO2/SBA-15 under mild conditions. The TiO2/SBA-15 was prepared by a facile incipient wetness impregnation method and characterized by N2 adsorption and X-ray diffraction. The CADS referred to ADS performance were evaluated in a batch reactor. High desulfurization uptake of 12.7 mg/g was achieved at low sulfur concentration of 15 ppmw-S by TiO2/SBA-15 under CADS, which was two-magnitude higher than that under ADS without the in-situ catalytic oxidation of dibenzothiophene. Kinetic results suggested that the CADS equilibrium over TiO2/SBA-15 was reached fast in 0.5 h. In the CADS-TiO2/SBA-15 system, the TiO2 loading, cumene hydroperoxide/dibenzothiophene ratio and CADS temperature were optimized to be 10 wt.%, 2, and 35 C, respectively. Furthermore, desulfurization tests in 5 consecutive CADS-regeneration cycles suggested that the bi-functional TiO2/SBA-15 can be regenerated by acetonitrile washing followed with oxidative air treatment. The superior desulfurization uptake at low sulfur concentration range, fast adsorption kinetics, excellent regenerability, operation at mild conditions, and facile and low-cost adsorbent synthesis make the CADS-TiO2/SBA-15 system an effective and economic desulfurization approach for ultra-clean fuel production..

	Abstract:Novel magnesium silicate double-walled hollow nanofibers (MSHNFs) with a hierarchical nanostructure have been successfully fabricated by combining the electrospinning technique with the hydrothermal method. The as-prepared MSHNFs are composed of numerous ultrathin nanosheets with a thickness of about 10 nm and have a high specific surface area and large pore volume. The MSHNFs exhibit high adsorption capacity and excellent stability in the purification test with organic molecules. Moreover, the MSHNFs could be easily recycled by gravitational sedimentation due to their unique one-dimensional nanostructural property.

	Abstract:The local structure of liquid water has been systematically investigated with Raman spectroscopy in a temperature range of 10 oC to 70 oC. It is found five spectra components respond differently to the temperatures. Comparison with the Raman spectra of little water in some organic solvents, the unbonded free -OH (-OD) stretching vibration band has been observed at ~3630 cm-1 (~2655 cm-1) in liquid water. With the aid of the theoretical calculations of larger kinds of water with different hydrogen bond pattern, the other strong spectra components have been identified and assigned to the -OH (-OD) stretching vibration band of the water molecules that form different kinds of hydrogen bond structure. Below the free OH stretching region, the four components were assigned as the vibration of the water molecules with the local structure of donor-donor-acceptor (DDA), distorted donor-donor-acceptor-acceptor (DDAA), ordered DDAA, and donor-acceptor- acceptor (DAA) configurations. Furthermore, the distribution of these kinds of water molecules and its temperature dependence have been derived from the reasonable spectral decomposition, which lead to the conclusion that the average number of shydrogen bond per water molecules in liquid is decreased from ~3.8 at 10 oC to ~3.5 at 70 oC.

	Abstract:A strategy is devised aiming to accurately and efficiently estimate the equilibrium hydrogen bond distances and interaction energies of complexes where the binding is dominated by hydrogen bonding. The strategy has included four essential ingredients of hydrogen bonding: the dipole-dipole interactions, the polarization interactions, van der Waals interactions and the covalency. The strategy can yield the equilibrium hydrogen bond distances and the interaction energies for hydrogen-bonded complexes as accurate as the high quality ab initio method MP2/aug-cc-pvTZ does, demonstrating the strategy proposed in this paper is reasonable. Base on the strategy, the components of the interaction energies for the hydrogen-bonded complexes are obtained and the nature of the hydrogen bonding is discussed. The strategy proposed in this paper has a definite physical meaning and points a new way for studying and understanding the hydrogen bonding in biosystems.
