Summary: A surface acoustic wave formaldehyde gas sensor was developed with a composite sensing layer of ZIF-8 on PEI/BC nanofilms, showing enhanced sensitivity and hydrophobicity. The addition of ZIF-8 increased the sensor's ability to detect low-concentration formaldehyde gas by preventing water interference and improving gas molecule adsorption. Experimental results demonstrated the sensor's stable response to changes in relative humidity, making it suitable for various environmental conditions.

Summary: Oxygen evolution reaction (OER) is a crucial half-reaction in water splitting and its slow kinetic process limits the efficiency of electrocatalytic water. Therefore, developing high activity OER electrocatalysts is essential for the advancement of water splitting. Zeolitic imidazolate framework-67 (ZIF-67) based compositions, with nitrogen-containing ligands, highly dispersed Co active sites, abundant Co-N bonds, tunable pore structure, and large surface area, have received extensive attention in the preparation of non-noble electrocatalysts for OER. Various modification methods, such as coordination environment optimization, morphology engineering, heteroatom incorporation, heterostructure construction, and hybridization, have been developed to construct ZIF-67 based electrocatalysts and regulate their active sites. This article summarizes the advanced modulation strategies on ZIF-67 based compositions for OER performance enhancement, highlighting the synthetic approaches, engineering principles, and catalytic mechanisms. The current challenges and prospects for developing the next-generation OER electrocatalysts are also discussed.

Summary: This work reports the construction of zinc-based zeolite imidazole framework (ZIF-8) microrings through an anisotropic growth-etching route. The method involves the deposition of ZIF-8 crystals on the edges of leaf-like ZIF-L nanosheets with coordinatively unsaturated Zn2+ and subsequent selective etching of alkaline unstable ZIF-L. Additionally, functional carbon materials with a ring-like structure can be prepared by pyrolysis of ZIF-8 microrings, exhibiting improved performance in oxygen reduction reaction. These findings may pave the way for the design of MOFs with sophisticated micro/nanostructures.

Summary: Enzymatic reactions have emerged as a promising alternative to traditional chemical catalysis for CO2 conversion. However, the use of enzymes is limited due to their fragility, instability, and lack of recyclability. Metal-organic frameworks (MOFs) have recently gained attention as immobilization scaffolds for enzymes. This review discusses the various forms of heterogeneity in enzyme/MOF systems and explores their benefits, synthesis strategies, and recent research progress. The integration of enzymatic systems and MOFs for CO2 conversion is also examined, alongside the challenges and potential future directions of biocatalytic CO2 conversion using MOF-based biocatalysts.
