摘      要：Sintering resistant noble metal nanoparticles are critical to the development of advanced catalysts with high activity and ***,we reported the construction of highly dispersed Pd nanoparticles loaded at the inner wall of ZrO_(2)hollow spheres(Pd@HS-ZrO_(2)),which shows improved activity and thermal stability over references in the Pd-ZrO_(2)(catalyst-support)*** after 800℃ high temperature calcination,the Pd nanoparticles and ZrO_(2)hollow spheres did not undergo morphological *** Pd@HS-ZrO_(2)manifests batter catalytic activity and thermal stability than the counterpart Pd/ZrO_(2)*** comparison to Pd/ZrO_(2)-800,Pd@ZrO_(2)-800 exhibits a 25℃ reduction in the temperature required for complete conversion of *** enhanced catalytic activity and thermal stability of Pd@HS-ZrO_(2)can be attributed to the nanoconfinement effect offered by the 10 nm wall thickness of the ZrO_(2)hollow spheres,which suppresses the coarsening of the Pd nanoparticles(active center for catalysis).
