Sm2MoO6/Ni(OH)2 was successfully immersed in water first, and the sensitizer is Eosin Y and the sacrificial agent is triethanolamine agent for high-efficiency photocatalytic production of H2. When Sm2MoO6 was loaded onto the surface of Ni(OH)2, the photocatalytic activity (2407.48 μmol g−1 h−1) was 2.6 times that of Ni(OH)2 (925.36 μmol g−1 h−1), which was Sm2MoO6 (169.36 μmol g−1 h−1) is 14.2 times. From a series of characterizations, Sm2MoO6 is an effective cocatalyst to improve the separation of photo-generated charges and the efficiency of electron transfer. Large specific surface areas are a primary requirement for high efficiency catalysts, and the catalyst is sufficiently into contact with the sensitizer and the sacrificial agent to soar the photocatalytic activity.Graphic AbstractThe first condition for an excellent catalyst is that it has a large specific surface area and can provide more active sites. In the dye sensitization system, the photocatalytic activity of Sm2MoO6/Ni(OH)2 is 2.6 times that of Ni(OH)2 and 14.2 times that of Sm2MoO6. Sm2MoO6 is an effective co-catalyst.

简单浸渍法合成Sm2MoO6/Ni(OH)2：非贵金属高效制氢光催化剂

Sm2MoO6/Ni(OH)2首先成功地浸入水中，敏化剂为曙红Y，牺牲剂为三乙醇胺剂，用于高效光催化制氢。当 Sm2MoO6 负载在 Ni(OH)2 表面时，光催化活性 (2407.48 μmol g-1 h-1) 是 Ni(OH)2 (925.36 μmol g-1 h-1) 的 2.6 倍，即Sm2MoO6 (169.36 μmol g−1 h−1) 是 14.2 倍。从一系列表征来看，Sm2MoO6 是一种有效的助催化剂，可以提高光生电荷的分离和电子转移的效率。大比表面积是高效催化剂的主要要求，并且催化剂与敏化剂和牺牲剂充分接触以提高光催化活性。图文摘要 优良催化剂的首要条件是比表面积大，能提供更多的活性位点。在染料敏化体系中，Sm2MoO6/Ni(OH)2的光催化活性是Ni(OH)2的2.6倍和Sm2MoO6的14.2倍。Sm2MoO6 是一种有效的助催化剂。
