Rational Design of Highly Efficient PdIn-InO Interfaces by a Capture-Alloying Strategy for Benzyl Alcohol Partial Oxidation.

Well-dispersed PdIn bimetallic alloy nanoparticles (1-4 nm) were immobilized on mesostructured silica by an in situ capture-alloying strategy, and PdIn-InO interfaces were rationally constructed by changing the InO loading and reduction temperature. The catalytic performance for benzyl alcohol partial oxidation was evaluated, and a catalytic synergy was observed. The Pd-rich PdIn-InO interface is prone to be formed on the catalyst with a low InO loading after being reduced at 300 °C.
