摘要
综述了提高TiO_2光催化氧化脱硫活性的各种方法。其中过渡金属Ni的掺杂有效地提高了TiO_2的催化活性。以TiO_2为载体、贵金属Pt和RuO2为活性组分或Cu-Fe为活性组分时,含硫化合物可被完全脱除。Ag改性的多壁碳纳米管与TiO_2复合脱硫率可达到100%。FeCl4离子液体与TiO_2结合脱硫率好且重复利用率高。构建TiO_2酶协同催化体系是可行的,但需进一步探讨。
The various methods of improving the catalytic activity of TiO_2-based photocatalytic oxidative desulfurization are presented.Among the transition metals Ni doped effectively improve the catalytic activity of TiO_2.When Pt,RuO_2 and Cu-Fe are loaded on TiO_2 as the active component,the sulfur-containing compounds can be completely removed.desulfurization rate can reach 100%for multiwalled carbon nanotubes modified with Ag and TiO_2 composite system.FeCl_4 ionic liquid combined with TiO_2 has good desulfurization rate and high recycle rate.It is feasible to construct a synergistic catalyst system of enzyme and TiO_2,but its needs further study.
