权利人:TOYOTA ENG & MFG NORTH AMERICA
摘要:A process of forming an oxygen evolution catalyst includes the steps of: providing Co(NO 3 ) 4 ; providing Na 2 WO 4 ; combining the Co(NO 3 ) 4 and Na 2 WO 4 forming a solution; exposing the solution to a source of microwave energy and initiating a hydrothermal reaction forming hydrated CoWO 4 . The oxygen evolution catalyst including hydrated CoWO 4 may be used to split water into oxygen and hydrogen ions.

摘要:A method for synthesizing cobalt oxide nanoparticles includes mixing an aqueous solution of a cobalt precursor and L-valine to obtain a reaction mixture and heating up the reaction mixture to temperature of at least 100° C. to obtain a dry powder. The method further includes calcining the dry powder to obtain the cobalt oxide nanoparticles. The cobalt oxide nanoparticles have an average particle size of 200 nm or less. The cobalt oxide nanoparticles are substantially spherical and include mesopores having a total pore volume of 0.1 to 0.5 cm3/g.
