3DOM CeO2-supported RuyM (M = Au, Pd, Pt) alloy nanoparticles with improved catalytic activity and chlorine-tolerance in trichloroethylene oxidation

The xRu_yM/3DOM CeO₂ catalysts are prepared using the PMMA-templating and PVA-protected reduction methods. The 0.93Ru_2.87Pd/3DOM CeO₂ exhibited excellent catalytic performance, hydrothermal stability, and chlorine-resistance for trichloroethylene oxidation.
