Preparation and application of bimetallic mixed ligand MOF photocatalytic materials

“…Again, using a one-pot strategy, Yang's team combined mixed metal (Ni/Co) and ligand (H 3 btc/ H 2 bdc) strategies to synthesize a series of bimetallic (NC-series) and hybrid metal/ligand (ML-series) MOFs for photodegradation of MB (Figure 42e,f). [418] It is well known that the conventional solvothermal form of PSE is time-consuming and energy-intensive. [419] A new skeleton Ti/Zr-UiO-66-M by promoting the rapid insertion of Ti IV into Zr 6 O 4 -clusters with microwave assistance was obtained by Tu et al [86] As a result, it can obtain Ti/Zr-UiO-66-M with an exchange rate of more than 50% in 4 h compared to the solvothermal method, which is much less than the former.…”

Benefitting from ultra‐high porosity, large specific surface area (SSA), and rich active sites, metal–organic frameworks (MOFs) have emerged as a star material in energy and environment related applications, especially in photocatalysis. In comparison with conventional photocatalysts, MOFs can be customized in terms of electronic structure, photo‐responsiveness, and morphological dimensions by rational design, which means that MOFs eliminate the need for other species to achieve enhanced photocatalytic performance, such as metals, compounds, and polymers, which may introduce extra costs, be time‐consuming, be multi‐phase, or have an unclear mechanism. Most previous review works related to MOF photocatalysis have mixed self‐tuning and assisted‐tuning, which often gives an incomplete understanding. In this work, the self‐tunning of MOFs by analyzing component (as clusters, ligands, and inclusions), defect (defect engineering, as linkers, clusters, and oxygen vacancies (OVs), and crystal (as facets, dimensions, and amorphization) is summarized. Then, outstanding examples of these strategies applied to water redox, CO2/N2 reduction, organic conversion, and environmental treatment are discussed. Finally, the opportunities and challenges faced in the self‐tuning of MOFs are analyzed from different perspectives. This paper is a comprehensive and systematic review on the self‐tuning of MOFs to enhance photocatalytic activity.

“…MOFs with multiple types of organic linkers enable structural selectivity 1 and are useful in a variety of applications, including gas storage and separation, as well as catalysis. [2][3][4] The option to select linkers with different and possibly helpful functionalities increases the potential for the creation of multi-functional frameworks. 5 A wide range of linkers, including di-and tri-carboxylate anionic linkers, have been reported in the literature.…”
