Abstract
A process of forming an oxygen evolution catalyst includes the steps of: providing Co(NO3)4; providing Na2WO4; combining the Co(NO3)4 and Na2WO4 forming a solution; exposing the solution to a source of microwave energy and initiating a hydrothermal reaction forming hydrated CoWO4. The oxygen evolution catalyst including hydrated CoWO4 may be used to split water into oxygen and hydrogen ions.
Claims21
