Summary: Ion-exchange processes can occur in several coordination polymers and their subclass of metal-organic frameworks. This study reports the synthesis and coordinated anion exchange of three new copper(II) coordination polymers under microwave-assisted hydrothermal conditions. These copper coordination polymers show good thermal stability and chemical stability, and can undergo anion-exchange reactions. They are also found to be efficient heterogeneous catalysts for the carboxylation of 1-ethynylbenzene with CO2 under mild conditions.

Summary: Under hydrothermal conditions, a Cd(II) coordination polymer (Cd-CP) was successfully synthesized using a flexible bis-triazole ligand and dicarboxylate ligand. The Cd-CP exhibits a one-dimensional chain structure connected by water bridges between adjacent cadmium ions. By further connecting the parallel one-dimensional cadmium chains with dicarboxylate ligands, a two-dimensional layer structure is formed. The bis-triazole ligands connect adjacent two-dimensional layers to form a final three-dimensional stacking structure. Theoretical computations and experimental fluorescence characteristics confirm the fluorescence properties of Cd-CP.

Summary: This review discusses the applications of Zn(II) carboxylate-based coordination polymers (Zn-CBCPs) in sensors, catalysts, infection and cancer treatment, as well as storage and drug-carrier materials. The luminescence properties of Zn-CBCPs, which are modulated by the nature of organic luminophores and their intermolecular interactions, allow for the sensing of various inorganic and organic pollutants. Zn-CBCPs, due to the Lewis acidity of Zn(II), can be used for dye elimination in wastewater through photocatalysis or inhibition of pathogenic microorganisms and tumors. Additionally, the porous structure of Zn-CBCPs enables the storage of gaseous or liquid molecules and improved drug delivery.

Summary: A series of novel alkaline anion exchange membranes (AEMs) have been developed with high stability and ionic exchange capacity (IEC), demonstrating promising applications in solid-state flexible rechargeable Zn-air batteries. The membranes show controlled water uptake and swelling ratio by adjusting the alkyl chain length, while longer chains hinder ion channel connectivity and phase separation affecting hydroxide ion conductivity. Additionally, the membranes exhibit high oxidation stability and retention rate after exposure to harsh conditions, showcasing their potential for long-term battery performance.

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.
