Heterogeneous bimetallic catalysts demonstrate enhanced catalytic performance compared with monometallic systems, as evidenced by flame spray pyrolysis synthesized Pd-Ru/CeO2 nanoalloys. Through precise control of Pd/Ru ratios, the optimized Pd0.5Ru0.5/CeO2 catalyst achieves complete CO oxidation at 120 °C. Advanced characterization uncovers two synergistic mechanisms─alloy-induced electronic redistribution confirmed by XPS analysis reveals interfacial charge transfer between Pd and Ru, while CO-TPD measurements demonstrate complementary adsorption behavior with Ru-dominated CO chemisorption and Pd-enhanced oxygen activation. The flame synthesis process simultaneously establishes strong metal-support interactions via CeO2 oxygen vacancy anchoring, stabilizing highly dispersed alloy nanoclusters. This study establishes flame spray pyrolysis as an effective strategy for engineering bimetallic catalysts with tailored electronic and structural synergy, providing a rational design framework for alloy-based oxidation systems.

Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
