Tuning the surface structure of supported PtNix bimetallic electrocatalysts for the methanol electro-oxidation reaction†
Abstract
The structures of PtNix nanoalloy particles were modified through thermal annealing in different atmospheres. The evolution of surface structures was uncovered by advanced transmission electron microscopy, and the structure–function correlation in methanol electro-oxidation was probed. It provided new insights into the design and synthesis of highly efficient electrocatalysts.
