Abstract
The present invention provides a catalyst for hydrogen peroxide decomposition with which hydrogen peroxide present in acid-containing water to be treated can be efficiently decomposed at low cost and which is less apt to dissolve away in the water being treated, can be stably used over a long period, and renders acid recovery and recycling possible. The present invention has solved the problems with a catalyst for hydrogen peroxide decomposition which is for use in decomposing hydrogen peroxide present in acid-containing water to be treated, the catalyst including a base and, a catalyst layer that is amorphous, includes a platinum-group metal having catalytic function and a Group-6 element metal having catalytic function and is formed over the base.
