The development of thermodynamically stable supported bimetallic catalysts for high-temperature reaction is significant and highly desirable but remains a grand challenge. In this work, we report a novel approach that relies on the interaction of metal nanoparticles with the support material to form unique bimetallic nanoparticles, which epitaxially anchor onto the support surface. Such unique nanostructured systems are catalytically active and ultrastable during selected catalytic reactions. In this paper, we describe the synthesis processes of ultrastable PtZn nanoparticles epitaxially anchored onto ZnO nanowires, which primarily consist of {10−10} nanoscale facets. Such anchored PtZn nanoparticles demonstrated good stability during high temperature treatments and selected catalytic reactions. The synthesis approach reported in this work provides a new strategy to develop thermodynamically stable supported bimetallic catalysts.
