In recent years, photocatalytic hydrogen production technologyAs a novel technology, the method has the advantages of low energy consumption, greenness, no pollution and the like, and is concerned. In an ideal photocatalytic water decomposition system, a photocatalyst can excite a large number of photo-generated electron-hole pairs under the irradiation of light, and after the photo-generated electron-hole pairs are separated, photo-generated electrons are used for reducing H+Hydrogen is generated and the holes are used to oxidize OH-Oxygen is generated. However, in practical applications, many catalysts lack oxygen evolution active sites and the entire reaction does not proceed properly. At present, most of photocatalytic hydrogen production works mainly by adding a large amount of hole trapping agents (mainly methanol, lactic acid and other reagents are used for trapping photogenerated holes). The photo-generated holes react with the hole-trapping agent, thereby ensuring that the photo-generated electrons are used to reduce H+Normal progress of the reaction path to generate hydrogen. At present, the rapid development of photocatalytic semi-hydrolytic water is realized by adding a hole trapping agent, but the smooth proceeding of the whole reaction can be ensured only by continuously adding the hole trapping agent in the photocatalytic semi-hydrolytic water process, so that the cost and the engineering difficulty of the reaction can be increased in the actual application process. Therefore, a novel full water-splitting photocatalyst is developed and prepared, hydrogen production and oxygen production by efficiently splitting water under the irradiation of sunlight are realized, and the photocatalyst has a better price advantage.
