Abstract:

Pd_xS_y is regarded as a undesirable product of metal palladium poisoning by sulfur-containing compounds, and hence has not received much attentions for many years. But in recent years, Pd_xS_ymaterial has been found to exhibit unique catalytic performance in catalytic hydrogenation, catalytic oxidation, electrocatalysis and visible light catalytic hydrogen production. In this paper, the traditional preparation method of Pd_xS_y material and the new green synthesis technology are compared. The research work of Pd_xS_y as catalyst in catalytic hydrogenation, catalytic oxidation, electrocatalysis and visible light catalysis for hydrogen production is also reviewed. It is found that traditional preparation method of Pd_xS_y material has the drawbacks of high toxicity, serious pollution, long cycle, etc., which has greatly limited its development prospect, so more in-depth innovative researches on the preparation method are required. At the same time, the excellent performance of Pd_xS_y material in many catalytic applications, especially in visible light photocatalytic hydrogen production, makes it a very promising catalytic material.

摘要：

在催化领域，Pd_xS_y多年来一直被认为是金属钯中毒形成的不良产物而不受重视。但是近年来，Pd_xS_y材料被发现在催化加氢、催化氧化、电催化以及可见光催化制氢方面表现出独特的催化性能。本文比较了Pd_xS_y材料的传统制备方法和绿色创新合成技术，综述了Pd_xS_y材料作为催化剂在催化加氢、催化氧化、电催化以及可见光催化制氢方面的研究工作。比较发现，Pd_xS_y材料的传统制备方法存在毒害大、三废多、周期长等缺点，这些缺点在很大程度上限制了该材料的发展前景，需要在制备方法上进行更深入的创新研究。同时，Pd_xS_y材料在多个催化领域，尤其是在可见光催化制氢方面的优异性能，使其在催化材料领域备受关注。
