Atomically dispersed Cu on Ce1−xRExO2−δ nanocubes (RE = La and Pr) for water gas shift: influence of OSC on catalysis†
Abstract
To elucidate the effect of CeO2 shape and doping on activity, Cu0.02Ce0.98O2−δ and Cu0.02Ce0.86RE0.12O2−δ (RE = La and Pr) were synthesized by a molecular precursor approach. The materials showed distinct activities depending on the shape and composition of CeO2, which was well correlated with their different oxygen storage capacities.
