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.
