Abstract
A sulfur-containing platinum-carbon catalyst, a preparation method thereof, and an application thereof are provided. The sulfur-containing platinum-carbon catalyst contains sulfur-containing conductive carbon black and a platinum metal loaded thereon. The total sulfur content in the sulfur-containing conductive carbon black is greater than or equal to the surface sulfur content, and the weight fraction of platinum is 20-70% by weight based on the total weight of the catalyst. The sulfur-containing platinum-carbon catalyst of the invention has a lower overpotential and a higher weight specific activity.
