Construction of Composite Photocatalyst ZnL/CN and Its Photocatalytic Degradation of Norfloxacin Wastewater Synergistic Hydrogen Production Performance

As a new catalytic technology, photocatalytic technology has received extensive attention in alleviating the energy crisis and controlling environmental pollution, and photocatalytic materials are the key to achieve efficient water splitting to produce hydrogen while removing organic pollution, so in this paper, [Zn(HL)(L)₂]·4H₂O (ZnL, HL = 2-(4-methoxyphenyl)-1H-imidazo[4,5-f][1,10] phenanthroline) was first synthesized and combined with g-C₃N₄ to form ZnL/CN, which were applied to the water splitting water to produce hydrogen in norfloxacin wastewater system. Through quantitative calculation, it can be found that ZnL and g-C₃N₄ have a matching band gap, which can form a heterojunction structure, and ZnL/CN built by the heterostructure solves the problem of photogenerated carrier recombination from the internal structure. On the other hand, through a series of related characterizations, it was further proved that 6% ZnL/CN has excellent photocatalytic performance, which lays a theoretical foundation for the research of ZnL/CN in the production of hydrogen from water splitting and environmental treatment and provides a research idea for the synergistic removal of organic pollutants from efficient water splitting to hydrogen.
