Synthesis of alumina supported Pd–Cu alloy nanoparticles for CO oxidation via a fast and facile method†
Abstract
Supported Pd–Cu alloy nanoparticles have been successfully synthesized via a fast, facile and environmentally friendly method by simultaneous reduction of Pd(NO3)2 and Cu(NO3)2. The catalyst contains Pd–Cu nanoparticles with higher alloying degree, smaller particle size, higher ratio of Pd0, Cu+, and chemisorbed oxygen species, and therefore exhibits enhanced CO oxidation activity.
