%X 硫化镉(CdS)因其具有良好的可见光响应能力和合适的导带位置,已被广泛应用于光催化产氢研究中。然而,单一CdS材料存在载流子复合较快及表面缺乏产氢活性位点等问题,极大地限制了其应用。在CdS表面负载助催化剂能够改善其表面的光生载流子的迁移行为,从而提升其光催化活性。在众多助催化剂中,过渡金属镍及化合物由于低成本、易合成且具有较好的析氢能力等特点而备受关注。本文主要介绍了基于CdS设计和制备的镍基光催化产氢助催化剂,阐述了其对CdS产氢活性的提升机制,最后对镍基助催化剂的发展方向进行了展望。
Cadmium sulfide (CdS) has been widely used in photocatalytic hydrogen production due to its excellent visible light response and suitable conduction band position. CdS has some disadvantages such as rapid carrier recombination and insufficient hydrogen-producing active sites on the surface, which largely limits its application in photocatalysis. Loading the cocatalyst on the surface of CdS is an effective method to improve the migration behavior of photogenerated carriers on the surface, which can eventually enhance its photocatalytic activity. The transition metal nickel and its compounds acting as cocatalyst have received intensive attention because of their low cost, facile preparation and high performance in hydrogen evolution reaction. This review mainly introduces the design and preparation of nickel-based photocatalytic hydrogen production cocatalyst based on CdS, and expounds its mechanism of improving the hydrogen production activity of CdS. Finally, the development direction of Ni-based cocatalysts is prospected.
