제목 | Effiective Tri-Metal and Dual-Doped Catalyst for Oxygen Evolution Reaction: Amorphous Co-Mn-Ni-P-B-O Nanoparticles |
초록 | Developinghigh-performance oxygen evolution reaction (OER) electrocatalysts is essentialbecause OER is critical in metal-air battery and water splitting and has slowkinetics. Therefore, OER catalyst are challenging for many researchers. In thisstudy, an OER catalyst is synthesized using a simple, low-cost method. It hasattractive features such as an amorphous phase and nano-sized structure,fabrication using three transition metals, and dual-doping using phosphorus (P)and boron (B). Dual-metal (CNPBO, CMPBO, NMPBO) and single-doped (CMNBO)comparison groups are prepared to confirm the efficiency of these features. Theuse of three transition metals and dual-doping causes metal-metal bonds toweaken, making the electrons move more easily. Accordingly, synthesizedCo-Mn-Ni-P-B-O nanoparticles exhibit outstanding intrinsic catalyticperformance. The overpotential for j10 and the tafel slope aredecreased 1.59 V, 62 mV/dec compared to dual-metal samples (1.64 V, 96 mV/dec). |
