Microscope analysis of Au-Pd/Ti[O.sub.2] glycerol oxidation catalysts prepared by deposition-precipitation method

Gold-palladium bimetallic nanoparticle catalysts prepared by a deposition-precipitation method were effective for aerobic oxidation of glycerol to carboxylic acids. The role of palladium was to suppress C-C bond cleavage that is responsible for the formation of C2 byproduct molecules. The nanopartic...

Zusammenfassung:Gold-palladium bimetallic nanoparticle catalysts prepared by a deposition-precipitation method were effective for aerobic oxidation of glycerol to carboxylic acids. The role of palladium was to suppress C-C bond cleavage that is responsible for the formation of C2 byproduct molecules. The nanoparticles were observed by microscope techniques, which further enabled characterizing the respective locations of Au and Pd within the particles.
