Preparation Condition Optimization and Characterization of PtNi/C Octahedral Nanocrystal Catalyst for ORR

On the basis of investigation about impacts of reaction temperature, reaction time and metal element ratio on the formation of PtNi octahedral nanocrystal, the preparation conditions were optimized, and PtNi/C octahedral nanocrystal catalyst with highly active (111) facets as surface was successfully prepared by a facile one-pot surfactant-free solvothermal method. The as-prepared PtNi/C octahedral nanocrystal catalyst exhibits well-defined...
