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.
