Octahedral Pt-Ni nanoparticles prepared by pulse-like hydrothermal method for oxygen reduction reaction

Herein, the pulse temperature is provided during the nucleation period of the nanoparticles to shorten the nucleation time for Pt-based nanoparticle growth. Herein, 3-nm-sized Pt-Ni alloy octahedral catalysts were prepared by pulse-like hydrothermal method. The influence of the pulse on nucleation is demonstrated by comparing the morphology obtained from the conditions of constant temperature and pulse temperature. It has been found that pulse...
