View the Complete Application at the US Patent & Trademark Office
Nanoparticles comprising a core including transition metal carbide, nitride, phosphide, sulfide, or boride and a noble metal shell can be made by transforming metal oxide core/noble metal shell materials coated in a ceramic material in a controlled environment. The noble metal shell can be a single monolayer. The self-assembly of metal carbide nanoparticles coated with atomically-thin noble metal monolayers results in a highly active, stable, and tunable catalytic platform.
