Surface engineering has been found to be effective in promoting the catalytic activities of noble‐metal‐based nanocatalysts. In this contribution, by using the PtCuxNi ternary alloy nanocrystal (NC) as the model catalyst, a surface tungsten(W)‐doping strategy, combining a surface oxidative acid treatment protocol, can effectively boost the electrocatalytic activities of the NCs in oxygen reduction...
Pt-based ternary alloy PtCuNi nanocrystals were synthesized through a highly straightforward and adaptable hydrothermal approach. By using appropriate combination of capping agents, the size of the nanocrystals can be controlled between 7–9nm with narrow size distribution, and their composition can be tuned in broad ranges. The composition and crystal structure of the nanocrystals were fully characterized...
