ACTIVE MATERIAL CONTAINING SN-SB-TRANSITION METAL ELEMENT, PREPARATION METHOD THEREOF, AND OZONE-GENERATING ELECTRODE CONTAINING THE ACTIVE MATERIAL

摘要

The present invention relates to an active material containing a Sn-Sb-transition metal element, a preparation method thereof, and an ozone-generating electrode containing the active material. In the active material, the mass ratio of the Sn element, the Sb element, and the transition metal element ranges from 200-900∶3-8∶0.1-4, in which the transition metal element is an element in the first transition metal series or the second transition metal series, the Sn element is sourced from a positive divalent Sn-containing compound, the Sb element is sourced from a positive trivalent Sb-containing compound, and the transition metal element is sourced from a transition metal element-containing compound at a stable valence state. The active material prepared by the invention is easy to store, has a simple preparation process, is easy to operate, and can be used as a catalyst for an ozone preparation process.
