| titleOfInvention | A kind of preparation method of oxygen evolution catalyst |
| abstract | The invention relates to the fields of catalysis and nanomaterials, and can be applied to metal-air batteries (such as zinc-air batteries, etc.) and fuel cells. Synthesized by co-precipitation method and simple hydrothermal method, firstly obtain manganese dioxide precursor by co-precipitation method and high temperature calcination, then add nickel nitrate hexahydrate and ferric nitrate nonahydrate through hydrothermal reaction to obtain the final catalyst: manganese dioxide /NiFe double hydroxide composite catalyst material. The preparation process of the catalyst is simple, and the required raw material reserves are abundant and the price is low. It shows excellent performance as a catalyst for oxygen evolution reaction. The oxygen evolution performance of the catalyst was tested in 0.1M alkaline potassium hydroxide solution, and the nano-cobalt disulfide/carbon composite catalyst material had a smaller overpotential (190mV) than the noble metal catalyst. |
