Abstract: Cadmium sulfide(CdS),which is a kind of visiblelight-response semiconductor catalyst with the band gap energy of 2.4 eV,is paid extensive attention in the field of photocatalytic reaction.The pure CdS is of low photocatalytic efficiency and easily photocorroded to lead to decrease its photocatalytic activity,which limit its application in the aqueous solution.It has been improved media for catalytic activity & stability of CdS semiconductor catalyst to load nano-CdS on the carriers with large specific surface area & easy exchange which prevent charger recombination.In this paper,preparation of nano-CdS loaded on SiO2,Al2O3,MgO,zeolite,macromolecular materials & layered oxides and their applications in H2 production of photocatalytic decomposition of water are summarized.

Key words: sadmium sulfide(CdS), loaded photocatalyst, water decomposition, hydrogen production
