ABSTRACT:
The present invention provides a process for producing hydrogen peroxide by reacting oxygen and hydrogen in a reaction medium catalytically using, as a catalyst, a tin-modified platinum group metal supported on a carrier. In the process using said catalyst, the presence of halogen and acid in reaction medium is unnecessary unlike the prior art methods, and hydrogen peroxide of high concentration can be produced efficiently. Thus, the present process has no restriction for reactor material as seen the prior art methods and further allows for easy purification of produced hydrogen peroxide.
