Summary: The pore dimension and surface property of porous materials play a crucial role in the transport of gases. To improve separation performance, it is important to design metal-organic frameworks (MOFs) with functional groups that can regulate the pore size. In this study, four MOFs (TKL-104-107) with different fluorination degrees were investigated for their adsorption behavior of C2H6 and C2H4. The fluorination of carboxyl at specific positions (ortho and meta) improved the selectivity and capacity of C2H6/C2H4 separation. The results suggest that purposeful functionalization of the pore surface can enhance the performance of MOF adsorbents for specific gas separation.

Summary: By designing and synthesizing a series of metal-organic frameworks (MOFs) with different pore environments, successful separation of sulfur hexafluoride (SF6) and nitrogen (N2) was achieved, which has the potential to reduce greenhouse gas emissions and bring economic benefits to the semiconductor industry. Among them, Ni(3-mpba)2 showed excellent SF6 uptake capacity and the highest SF6/N2 selectivity. X-ray diffraction analysis and theoretical calculations revealed that introducing a methyl group into Ni(3-mpba)2 altered the microchemical environment of the pores, resulting in a smaller pore structure and more binding sites that enhance the affinity between SF6 and the adsorbent.

Summary: This study investigates the chemical ordering in Ni(Co)MnTi alloys using neutron and x-ray diffraction techniques. It is found that there is no Heusler-typical L2_1 order between Ti and Mn, and there is no ordering among Co and Ni atoms. However, the phase transition of Co containing samples can be significantly altered by changing the degree of B2 order with proper heat treatment.

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.
