Abstract Carbonaceous nanospheres anchored with PtxNiyCoz alloy nanoparticles (PtxNiyCoz /CA) was obtained by a two-step hydrothermal approach. Multiple characterizations confirmed that oxygen functionalized groups on the surface of the carbonaceous sphere could deeply anchor the PtxNiyCoz alloy nanoparticles, which prevented the further growth of alloy particles and formed a stable interface between the alloy particle and carbonaceous supporter. Accordingly, as-prepared PtxNiyCoz/CA electrode exhibited superior electro-catalytic performance in multiple electrochemical reactions, including MOR, ORR, and OER, due to the optimal interfacial effect.

用 PtxNiyCoz 合金纳米颗粒深度锚定的富氧碳质纳米球作为多功能电催化剂

摘要 通过两步水热法获得了锚定 PtxNiyCoz 合金纳米粒子 (PtxNiyCoz /CA) 的碳质纳米球。多项表征证实，碳质球表面的氧官能团可以深深地锚定 PtxNiyCoz 合金纳米颗粒，阻止合金颗粒的进一步生长，并在合金颗粒和碳质载体之间形成稳定的界面。因此，由于最佳的界面效应，所制备的 PtxNiyCoz/CA 电极在多种电化学反应中表现出优异的电催化性能，包括 MOR、ORR 和 OER。
