	Abstract:The porous carbon material prepared from naturally abundant bamboo shoot shell for the application of supercapacitor is put forward. It not only makes waste biomass to be profitable, but also provides a sustainable development way for the preparation of the new porous carbon material. The physicochemical and electrochemical properties of the as-prepared porous carbon samples are studied in detail. The results show that the porous carbon sample prepared at 5:1 weight ratio of KOH to bamboo shoot shell derived carbon (BSSDC) exhibits a specific surface area of ~ 3408 m2 g-1 (BSSDAC-5). In addition, the BSSDAC-5 shows a high specific capacitance of 308 F g-1 at 1 A g-1 and high capacitance retention of 97.40% even after 10000 cycles, indicating its potential application for high-performance supercapacitors.

	Abstract:Through upconversion process, rare earth ion-doped upconverters could emit visible light under the excitation of the infrared light, which falls into the absorption range of quantum dots. Therefore, it is reasonable to combine upconverters with quantum dot-sensitized solar cells (QDSSCs) to indirectly utilize infrared light for extending the light absorption ability of quantum dots and enhancing the photoelectric conversion efficiency of QDSSCs. Yb, Tm co-doped YF3 (Ln-YF3) has been integrated into the photoanodes for quantum dot-sensitized solar cells (QDSSCs). Compared with the control electrode of pure P25, the photoanode with Ln-YF3 exhibits an enhanced photovoltaic performance with an short-circuit current of 11.26 mA/cm2 and a power conversion efficiency of 3.57 %. UV-Vis reflection spectrum as well as the incident photon to charge carrier efficiency (ICPE) measurement results indicate that no obvious light scattering effect occurs in the photoanode with Ln-YF3, indirectly confirming the upconversion-induced enhancement in the photovoltaic performance of the QDSSCs based on the photoanode with upconverters.

	4. Metal Triangles versus Metal Chains and Terminal versus Bridging Hydrogen Atoms in Trinuclear Osmium Carbonyl Hydride Chemistry

	Abstract:The chemistry of trinuclear osmium carbonyl hydrides is a rich area with the three H2Os3(CO)n derivatives (n = 12, 11, 10) all being known stable compounds ultimately obtained from Os3(CO)12 and hydrogen under various conditions. Density functional theory studies on the H2Os3(CO)n systems (n = 12, 11, 10, 9, 8) predict the experimentally observed species for n = 12, 11, and 10. These include a linear structure for H2Os3(CO)12 and triangular structures for H2Os3(CO)11 and H2Os3(CO)10. However, the H2Os3(CO)11 system is predicted to be a fluxional system with the four lowest energy isomers lying within 2 kcal/mol of energy. Three of these H2Os3(CO)11 isomers, all with one terminal hydrogen and one bridging hydrogen, have been observed experimentally by NMR. The lowest energy of these isomers has been isolated and structurally characterized by X-ray crystallography. In contrast to H2Os3(CO)11, the lowest energy H2Os3(CO)10 structure, namely the known structure with an Os=Os edge bridged by both hydrogen atoms and all terminal CO groups, lies ~10 kcal/mol below the next lowest energy isomer. The predicted CO dissociation energies of the H2Os3(CO)n derivatives (n = 12, 11, 10) suggest this H2Os3(CO)10 structure to be the "thermodynamic sink" in the H2Os3(CO)n systems consistent with its synthesis from Os3(CO)12 and H2 at 120 C and atmospheric pressure. The lowest energy structures of the more highly unsaturated H2Os3(CO)n (n = 9, 8) can be derived from this (μ-H)2Os3(CO)10 structure by removal of CO groups from the osmium atom remote to the doubly bridged Os=Os edge of the Os3 triangle with relatively little change in the central (μ-H)2Os3 triangle geometry.

	Abstract:Naphthopyran and its derivatives were synthesized and used as ultraviolet absorbent in photo-oxidation of poly(ethylene oxide) (PEO). The absorption spectra of naphthopyran before and after irradiation of UV light illustrated that the absorbance of naphthopyran covered a wide range of wavelengths, especially in UV light range. The studies of infrared spectra, differential scanning calorimetric and thermogravimetric analysis proved that the addition of naphthopyran greatly reduced the photo-oxidation speed of PEO.

	Abstract:Perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) are difficult to remove from the water environment due to their inertness to photolysis, hydrolysis, and biodegradation. In the study, the rapid decomposition of PFOS and PFOA was found in the presence of Sr-β-Bi2O3 as a photocatalyst under visible light irradiation. Compared with nano-TiO2 and direct photolysis, the photocatalysis by Sr-β-Bi2O3 can remove PFOS and PFOA more efficiently. In 1.0 h, about 72.3% of PFOS and 60.1% of PFOA ([PFOS]i = [PFOA]i = 100 μgL-1) can be removed from the aqueous solution under visible light irradiation (λ > 440 nm). The effects of temperature, pH, and initial PFOS/PFOA concentration on the photocatalytic decomposition rates were investigated. Sequentially, the intermediate products were identified as PFO (C8F17), PFHe (C6F13), PFPe (C5F11), PFBu (C4F9), PFPr (C3F7), PFHpS (C7F15SO3), and PFHeS (C6F13SO3). Based on the detection of reactive radicals, photocatalytic reduction by hydrated electron was determined as the major degradation route. The detailed defluorination pathway was also proposed.

	Abstract:In this paper, we report the design of numerous models for silicon-doped ternary cationic carbon clusters HCnSi2+ (n = 1-9). By means of the B3LYP density functional method, we performed geometry optimization and calculation on vibrational frequency. The ground-state (G-S) isomers of even-n HCnSi2+ (n = 1-9) are found to be structures with the hydrogen atom and a Cn-2Si chain each bonded to a carbon atom of a C2Si ring. The structures of the G-S isomers of odd-n HCnSi2+ (n = 1-9) are "Y" shaped with one silicon atom and the hydrogen atom located at one end of the Cn chain, and another silicon atom located at the other end. The Cn chain (Cn-2 chain for even-n ones) of the G-S isomers of HCnSi2+ (n = 3-9) displays a polyacetylene-like structure. It is found that the G-S isomers of even-n HCnSi2+ (n = 1-9) are more stable than the odd-n ones. The finding is in accord with the relative intensities of HCnSi2+ (n = 1-9) recorded in mass spectrometric investigations. We provide explanations for such a trend of even/odd alternation based on concepts of the bonding character, incremental binding energy, ionization potential, proton affinity, and dissociation channels.

	Abstract:A green and environment-friendly method for synthesis of metal nanoparticles (NPs) was presented. Sesbania gum (SG) as a reducing and stabilizing reagent was first employed to prepare metal NPs. Through solvent evaporating of the Ag NP contained solution, a stable metal NP embedded membrane was obtained. Fourier transform infrared (FT-IR) and Raman spectroscopies were employed to insight into the interaction between metal NPs and SG in membrane. Interestingly, the dried metal NP embedded membrane can be redissolved into water to form a homogeneous Ag colloid according to the protection of SG. This study provides a green and low cost approach for synthesis of metal NPs. The existence of this metal NP embedded membrane makes the conservation and transportation of NPs become easy and facile.

	Abstract:Anatase TiO2 nanorods with exposed {100} facets were prepared by employing simple NaCl assisted hydrothermal technique from hydrogen titanate nanosheet precursor. The structural characteristics and formation mechanism of the anatase TiO2 nanorods was deduced from XRD, SEM and TEM characterizations, which revealed that formation of TiO2 nanorods were derived from a combined effect of phase transition retard from hydrogen tiantate to anatase TiO2 induced by Na ion and selective adsorption of Cl ion on the{100} facets of anatase TiO2 crystals. Photocatalytic performance indicated that the TiO2 nanorods with high-energy {100} facet exposure exhibit much higher activities than that of rhombic nanoparticles with low-energy {101} facet exposure for the degradation of organic contaminants.

	Abstract:Amphiphilic lipid molecules can form various micelles depending on not only their molecular composition but also on their self-assembly pathway. As a continuation of the previous work [J. Chem. Phys. 2009, 130, 094905], the micellization behavior of a small lipid droplet composed of dipalmitoylphosphatidylcholine (DPPC) and hexadecylphosphocholine (HPC) is systematically investigated using coarse-grained molecular dynamics. In our current simulation, various micelles such as spherical and oblate vesicles, disk-like micelles, double or single ring-like and worm-like micelles were obtained by varying the proportion of the two components and the size of lipid droplets. Through analysis of the micelle structure and the evolution pathway, we found that oblate vesicles were an unstable state which could slowly swell into a spherical vesicle by the diffusion of water across the vesicles' boundary. In the initial state, the lipid droplets favored forming oblate vesicles and ring-like micelles due to in situ micellization. Our results demonstrated that special initial conditions, combined with various molecular compositions, could be an effective way to tune the micellar morphological structure.
