Ternary metal chalcogenides hollow tube derived from MOF sulfurization for photocatalytic hydrogen generation from water and tetracycline wastewater

A good approach to addressing global warming and the energy crisis is to use semiconductor photocatalysts for water splitting to produce valuable fuels such as hydrogen. In this study, different photocatalysts (ZIS1, ZIS2, ZIS3 and ZIS4) derived from different degrees of sulfidation of In-MOFs were made via the hydrothermal method . Among them, ZIS2 owned the best photocatalytic hydrogen production performance (3.45 mmol h −1  g −1 ). Additionally, this study also investigated the photocatalytic hydrogen production performance of ZIS2 in tetracycline (TC) wastewater systems. In 10  mg L −1 of TC wastewater, the H 2 generation rate reached 98.34 μmol g −1 , and 95.27 % of the TC was removed after 4 h. Characterization techniques revealed that the hollow tubular structure in ZIS2 sample played a crucial role in internal charge transport, thereby influencing the photochemical reaction of photogenerated particles. The research on the structure-properties of the ZIS2 hollow tubular was expanded in the field of photocatalytic application, and its possible use in the area of solar fuel transition was also expanded.
