摘要： 光催化分解水产氢是一种利用太阳能的理想形式。为了大规模推广光催化分解水产氢,当前急需解决的问题是制备一种低成本、不含有贵金属的光催化剂。本文通过结合P元素掺杂与MoS2助催化剂的原位光沉积,制备出基于CdS纳米棒的高效且稳定的光催化体系,并用于光催化分解纯水产氢。所制得的CdS/P/MoS2体系展现出比未改性的CdS更强的光催化活性和稳定性,其在蒸馏水中的光催化产氢速率达到692.9 μmol/(g·h),且在波长420 nm处的表观量子效率(AQE)为0.31%。

Abstract: Photocatalytic water splitting is an ideal way to utilize solar energy. In order to popularize photocatalytic water splitting on a large scale, the current problem to be solved is to prepare a low-cost photocatalyst without noble metals. An efficient and stable photocatalytic system based on CdS nanorods for photocatalytic water splitting was successfully constructed by combining P element doping with in-situ photodeposition of MoS2 cocatalyst. The prepared CdS/P/MoS2 system showed stronger photocatalytic activity and stability than the unmodified CdS. The photocatalytic hydrogen production rate of CdS/P/MoS2 in distilled water reached 692.9 μmol/(g·h), and its apparent quantum efficiency (AQE) at 420 nm was 0.31%.

Key words: cadmium sulfide, phosphorus doped, molybdenum disulfide, photocatalytic hydrogen production, non-noble metal
