Harnessing solar energy through photocatalysis has excellent potential for powering sustainable chemical production, supporting the United Nations' environmental goals. Single-atoms (SAs) dispersed on catalyst surfaces are gaining attention their highly active and durable nature. Metal-organic frameworks (MOFs) can provide enough reactive sites to sustain selectivity durability over time because of tunable channels functional groups. Owing organized structures, MOFs ideal platforms securing individual atoms promoting solar-driven reactions. Few reviews have, however, reflected possibility combining SAs produce potent photocatalysts that may clean fuels valuable chemicals. This review provides a general overview methods generate photocatalysts. The challenges associated with these MOF-based single-atom systems also critically examined. Their future development is discussed as continued refinement helps more fully leverage advantages boosting photocatalytic performances - turning sunlight into chemicals in manner supports development. Insights gained here could illuminate pathways toward realizing profound empower production driven by renewable energy.

Metal–organic frameworks (MOFs) have been used in triboelectric nanogenerators (TENGs) to improve the output performance because of their designability and great triboelectricity. However, there still lacks detailed systematic research about influence morphology MOFs outputs TENGs. Here, ZIF-67 particles with three different sizes were successfully prepared filled silk fibroin (SF) prepare composite films. TENGs composed ZIF-67/SF composites assembled tested. Results indicated that was very sensitive filler particle size mass ratios. Owing much higher charge-trapping property, smallest (500 nm) increased power density by 5 times value 144 μW cm–2. With enhanced density, based on films applied more widely for harvesting mechanical energy real life.

Contact-electro-catalysis (CEC) usually uses polymer dielectrics as its catalysts under mechanical stimulation conditions, which although has a decent catalytic dye degradation effect still warrants performance improvement. A carrier separation promotion strategy based on an internal electric field by polarization can effectively improve ferroelectric material in photocatalysis and piezocatalysis. Therefore, necessary process of CEC also be promoted is largely expected to theoretically. However, the enhancement not been achieved experiment yet, because difficulty building inert dielectric.
