“…As a kind of metal oxide semiconductor material, ZnO has attracted tremendous attention in the field of gas sensing in recent years, with the characteristics of easy fabrication, diverse morphology, and the ability to be compounded with a variety of materials. , However, the shortcomings of pure ZnO-based gas sensors, such as high working temperature, low sensitivity, and poor selectivity, still exist and need to be further improved. − Meanwhile, as the latest type of porous material with abundant potential applications, metal–organic frameworks (MOFs) possess unique crystalline porosity with a periodic network structure formed by the self-assembly of transition-metal ions and organic ligands . On account of the advantages of low density, large specific surface area, regular and adjustable pore size, diverse topology structure, and capable of cuttability, it is often utilized as the starting template in the process of material design and synthesis. − For example, the BiVO 4 –MOF photoanode obtained by the in situ modification of BiVO 4 with Co-MOF has excellent photoelectrochemical water oxidation performance properties .…”
