光催化氧化脱硫催化剂研究进展

近年来,光催化氧化脱硫在清洁燃料生产领域受到了广泛关注,光催化氧化脱硫催化剂的开发也成为热点研究课题。对纯相、掺杂型、负载型和异质结型光催化氧化脱硫催化剂的制备方法、结构、性质特点以及催化脱硫性能进行综述。由于纯相催化剂的光响应范围比较窄，掺杂型、负载型和异质结型催化剂通过降低催化剂的禁带宽度可以扩大光波响应范围。指出负载型催化剂不但可以扩大光波响应范围，还可以具有更高的比表面积，从而进一步提高催化剂的活性。因此，低成本载体的研究和光催化氧化脱硫催化剂再生性能的研究是未来的重要研究方向。

Progress in Photocatalytic Oxidation Desulfurization Catalysts

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.
