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MoS_(2)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/MoS_(2)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692.9μmol/(g·h),且在波长420 nm处的表观量子效率(AQE)为0.31%。
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 MoS_(2) cocatalyst.The prepared CdS/P/MoS_(2) system showed stronger photocatalytic activity and stability than the unmodified CdS.The photocatalytic hydrogen production rate of CdS/P/MoS_(2) in distilled water reached 692.9μmol/(g·h),and its apparent quantum efficiency(AQE)at 420 nm was 0.31%.
