	1. Water-medium Barbier Reactions over the Mesoporous Pd(II) Organometal Catalyst with Crystal-like Pore Walls and High Stability

	Abstract:A new approach was developed to prepare an immobilized Pd(II) organometallic catalyst with mesoporous structure by surfactant-directed co-condensation between biphenyl-bridged organosilane and Pd(II) organometallicsilane. Both the Pd(II) organometallic complex and the biphenyl groups were embedded in the pore wall, which could diminish the blockage of mesoporous channels. As a result, such catalyst exhibited high activity and selectivity in water-medium Barbier reactions owing to the high surface area, large pore size and strong surface hydrophobicity resulting from biphenyl functionaliztion, which facilitated the diffusion and adsorption of organic reactant molecules on the active sites. Meanwhile, the as-prepared catalyst also displayed long durability owing to the crystal-like mesoporous wall resulting from the π-π stacking of biphenyl groups, which could protect the mesoporous structure from collapsing in aqueous Barbier reactions.

	Abstract:The catalytic activity of Fe/ZSM-5 for the selective reduction of NO to N2 with methane in the presence of excess O2 was studied. Fe/ZSM-5 with various Fe loadings were prepared by impregnation method. It was well known that methane is inactive when Fe/ZSM-5 as the catalyst for the SCR of NO with methane. However, this letter shows that when the content of Fe was about 0.5%, Fe/ZSM-5 showed higher catalytic activity and selectivity of methane, and put forward measurable activation for CH4 is a important factor for the reaction of removal of NOx with CH4.

	3. DMC Formation over CexZr1-xO2 Prepared by Complex-Decomposition Method

	Abstract:A series of bimodal porous CexZr1-xO2 (x = 0.2, 0.3, 0.4, 0.5, 0.6, 0.8, 1.0) solid solutions were prepared by complex-decomposition method. The results of XRD, Raman, SEM, mercury porosimetry and N2 adsorption/ desorption measurements indicated that the physical properties of the solid solutions were significantly affected by the Ce/Zr molar ratio and the calcination temperatures. The Ce0.5Zr0.5O2 solid solutions presented bimodal mesopores with narrow pore size distributions (PSD). These solid solutions can be used in dimethyl carbonate (DMC) synthesis from methanol and CO2. Results indicated that calcination temperatures and the molar ratio of CexZr1-xO2 were the key factor in determining the catalytic activity for DMC synthesis. It exhibited higher catalytic performance to DMC when the molar ratio of Ce to Zr is to be of 1.0 under the calcination temperature of 1273 K. However, the methanol conversion is still low which is limited by the reaction equilibrium. The addition of 1, 1, 1-trimethoxy methane (TMM) was engaged to consume H2O produced in synthesis of DMC, and found that it was very effective for the increase in the methanol conversion from 1.8 to 7.85% under 377 K, 20 MPa and 24 h. The combination of the bimodal porous catalyst with an effective H2O removal agent for the reaction system can provide a novel process of selective DMC production directly from CO2 and CH3OH with dramatic efficiency for the maximum CH3OH conversion of 10.4%. The mechanism of the direct synthesis of DMC from CO2 and CH3OH with the additive of TMM over CexZr1-xO2 catalyst was also discussed.

	Abstract:The effects of zeolite NaY dosage, pyrolysis time and pyrolysis temperature on the pyrolysis of pubescens were investigated. It was found that the presence of zeolite NaY greatly enhanced the yield of liquid products and remodeled the distribution of the pyrolytic liquid products directing to a good selectivity to acetic acid, and different liquid monomers could be acquired by controlling the pyrolysis temperature and pyrolysis time. The increase of liquid yield could be attributed to the catalytically selective conversion of primary pyrolytic intermediates to form liquid products instead of the formation of gaseous products or coke in the absence of catalyst. It was shown that when the ratio of zeolite NaY/Pubescens was below 1:1, the decomposition of several intermediate species leading to gaseous products passed the high temperature reaction zone directly without being altered by the catalyst, leading to equivalent amount of gaseous products formed. When zeolite NaY/pubescens ratio increased over 1:1, those species leading to gaseous products by thermal decomposition underwent catalytic pyrolytic conversion and gave out liquid products. The deactivation of the zeolite NaY was also tested. Zeolite NaY was deactivated after four repeated runs. XRD (X-ray diffraction) results showed that several diffraction peaks of zeolite NaY were intensified while certain others were weakened by 10 hours pyrolysis at 873K. The deactivation of zeolite NaY was caused by the variation of the crystalline structure and the deposition of coke formed in the repeated runs as revealed by XRD and SEM.

	Abstract:A simple and efficient route is reported for the synthesis of mesoporous carbon materials via carbonization of a kind of composite containing citric acid and aluminum phosphate (CA/AlPO). The pore size of the mesoporous carbon can be tuned in a certain range by addition of suitable amount of sucrose into the CA/AlPO composite. The characteristic results show that these carbon material possesses uniform pore size distribution and graphitic phase characteristic. The mesostructured AlPO, which is in-situ formed during the carbonization process, can be regarded as a hard-template for the formation of porous carbon material. The uniform distribution of citric acid, and the suitable interaction between citric acid and aluminum phosphate play important roles in the growth process of carbon network.

	Abstract:In this work, various supported platinum catalysts (Pt/MeOx, Me= Fe, Zn, Al, Ni) were prepared by colloid deposition method, and their catalytic properties for the low-temperature CO oxidation were investigated. It was found that the type of support has considerable effect on the activity of the catalysts. The addition of water vapor in feed stream has the positive influence on the activity of the catalysts. Under an optimized tested condition, Pt/Fe2O3 shows unusual low-temperature activity and long-term stability, and it can completely transform CO into CO2 at room temperature in the presence of water vapor for more than 3000 h.

	Abstract:The oscillatory behavior over the Rh/H-ZSM-5 catalyst was firstly reported at atmospheric pressure during the partial oxidation of methane. Temperature programmed techniques such as TPO and TPR were performed to look into the reaction mechanism. The results obtained from the experimental studies indicate that the synergism of the coke of some kind of stable form and the oxide which could be switching back and forth from the reduced state to the oxidized state is responsible for the oscillatory behavior seen in this system.

	Abstract:Oxygen glow discharge has been used for treatment of Pd/HZSM-5 catalyst in order to investigate the catalyst reduction mechanism during gas discharge treatment. XRD and XPS characterizations demonstrate that the catalyst treatment using oxygen glow discharge leads to a reduction of Pd ions. This suggests that the electronic effect plays an important role in the treatment of catalyst using glow discharge. A highly durable catalyst for methane combustion has been obtained from the calcination of the glow discharge treated sample. The present investigation further confirms that the glow discharge treatment followed by calcination can lead to an excellent catalyst preparation with high dispersion, excellent low-temperature activity and enhanced stability for methane combustion catalytically.
