Nghiên cứu chế tạo điện cực compozit oxit spinel NixCo3-xO4/polypyrol xúc tác phản ứng khử oxy

Abstract

In this work we have studied the polypyrrol/oxide (Ppy/oxit) composite films electrodeposited on glassy carbon for electrocatalyst application of oxygen reduction reaction. Three oxides used NiO, Co₃O₄ and Ni_0.3Mn_2.7O₄ with very small size was prepared by thermal decomposition of nitrate salts. These oxides were incorporated in the polypyrrole films during the electrodeposition respectively to form Ppy/oxide composite films. Among the composite films obtained the polypyrrole/Ni_0.3Mn_2.7O₄ gives the best electrocatalytic effect.
