Abstract

The invention relates to a Ru and / or Ir noble metal oxide with a molecular formula expressed as Ru*Ir1-xO2, wherein x satisfies the relation of: 0<=x<=1. The noble metal oxide is prepared by using an amino modified silicon oxide molecular sieve SBA-15 as a template, and impregnating and reducing the Ru and / or Ir noble metal into surrounding holes of the template housing by Coulomb and capillary effect. The method is a simple preparation method of noble metal oxide with controllable morphology, and applies a hard template method to preparation of binary noble metal oxide to expand its scope of application. The Ru*Ir1-xO2 prepared by the invention shows good oxygen evolution electro-catalysis performance when used as a solid polymer electrolyte (SPE) water electrolyzer anode catalyst. The invention has extensive application value in regenerative fuel cell (RFC), photoelectric catalysis and electrolysis hydrogen generator device.

Description

technical field

[0001] The invention relates to an oxygen evolution electrocatalyst Ru and / or Ir noble metal oxide, specifically a kind of noble metal oxide prepared by using amino-modified silicon oxide molecular sieve without surfactant as a template, which can be applied to SPE water electrolysis , RFC or oxygen evolution electrocatalyst in various electrolysis devices. Background technique

[0002] In recent years, SPE water electrolysis technology has become a research hotspot in the field of hydrogen production due to its advantages of high efficiency, zero emissions, compact structure, environmental friendliness, and high product purity. Moreover, the high-purity oxygen produced by it has also been used in aerospace, medical treatment, and analysis. and other fields. However, the high price is the main reason that restricts the further commercial application of SPE water electrolysis technology. Therefore, how to reduce the cost and improve the electrolysis efficienc...
