In recent years, the development of photocatalytic desulfurization catalyst has been a hot topic in the field of clean fuel production. The preparation method, structure, properties and catalytic desulfurization performance of pure phase, doped, supported and heterojunction photocatalytic oxidation desulfurization catalysts were studied. Due to the narrow light response range of pure phase catalysts, doped, loaded and heterogeneous junction catalysts have the expanded light wave region by reducing the bandgap width of catalysts. It is pointed out that the supported catalyst can not only expand the range of light wave range, but also increase the specific surface area of the catalyst and then further improve the activity of it. However, the study of low cost carriers and the regeneration performance of photocatalytic oxidation desulfurization catalysts are important research directions in the future.
