Summary: Zeolite-templated carbon (ZTC), a three dimensional ordered carbon material, was synthesized and used as an efficient adsorbent for the removal of volatile organic compounds (VOCs). The ZTC sample prepared at 600 degrees C for 7 h exhibited the largest specific surface area and the best adsorption capacity for toluene, benzene, and m-xylene. The presence of O-2, SO2, and H2O influenced the adsorption capacity of VOCs, with O-2 initially promoting the removal ability and H2O having the most inhibitory effect.

Summary: The functionalization of Na-X zeolite with 1-butyl-3-methylimidazolium bis(triflouromethylsufonyl)imide (IFZ) was studied for its ability to remove heavy metals and dyes from water. The IFZ exhibited a reduced surface area and pore volume compared to the parent zeolite. It showed better adsorption of dyes than metal ions under acidic conditions. The Langmuir isotherm and pseudo-second order models provided accurate descriptions of the equilibrium data. The adsorption process was found to be endothermic and spontaneous. The IFZ can undergo multiple cycles of desorption and regeneration. Therefore, this modified zeolite can be used for the removal of various pollutants from water in a simple step.

Summary: This study investigated the effect of nitrogen doping on the adsorptive removal of sulfur compounds from model fuel. Nitrogen doping improved the surface area and pore volume of templated carbon, thereby enhancing the adsorption capacity of sulfur compounds. The adsorption-regeneration cycles showed that the removal efficiency was only lowered by 4-10% after five cycles.

Summary: MOF materials with adjustable pore structure and polymetallic sites have been explored as electrocatalysts for OER. Bimetallic materials show higher electrocatalytic activity than monometallic materials, while carbon-coated and doped MOF catalysts exhibit stable and good OER activity. The synergistic interaction between polymetallic active sites effectively improves the intrinsic activity of MOF on OER.

Summary: This study investigates the evolution and autoreduction behavior of Cu species in CuCl/NaY adsorbent during vacuum thermal activation. It is found that Cu species migrate from supercages to the nearby plane of the six-membered ring connecting the supercage and sod cage during vacuum activation. At 150 degrees C, vacuum autoreduction occurs, resulting in the formation of Cu+Cl- species. The results provide reference for the preparation of pi-complex adsorbents.

Summary: Hierarchical porous system with two types of mesopores provides a solution to the diffusion limitation in conventional zeolites. Cobalt oxide impregnated hierarchical ZSM-5 zeolite samples with intra- and inter-crystalline mesopores were synthesized using two different strategies. The physicochemical properties of the modified catalysts were analyzed, revealing distinct features given by the two mesoporous configurations. Catalytic activity analysis showed that Co-oxide/ZSM-5 with inter-crystalline mesopores exhibited higher activity in methane partial oxidation reaction compared to Co-oxide/ZSM-5 with intra-crystalline mesopores.

Summary: First principles calculations were used to investigate the pathway for methylation of benzene with methane catalyzed by MFI type zeolite-supported Co species. The strong adsorption of benzene on Co is found to lower the activation energy for methane dissociation and promote the formation of toluene precursor.
