Chemoselective Hydrogenolysis of Glycerol Catalyzed by Platinum on Carbonaceous Supports

Oberhauser W., Evangelisti C., Psaro R., Vizza F., Bevilacqua M., Filippi J., Lavacchi A., Marchionni A., Miller H.A., Machado B.F., Serp P., CNR-ICCOM, IT

Glycerol has been selectively converted into 1,2-propandiol in the presence of dihydrogen and heterogeneous Pt-based catalysts. These latter catalysts consist of small-size Pt-nanoparticles (NPs) (i.e. 1.0-1.5 nm,) obtained by a metal vapor synthesis, supported on [...]

Comparing the Effect of 2nd Row Dopants on the Carbon Support to improve Pt Catalytic Activity and Durability

Groves M.N., Chan A.S.W., Malardier-Jugroot C., Jugroot M., Malardier-Jugroot C., Royal Military College of Canada, CA

This work outlines improvements to the Pt catalyst durability and activity by modifying the carbon catalyst support for use in the proton exchange membrane fuel cell. Computational methods have shown that nitrogen and boron dopants [...]

Characterization and Synthesis of Platinum Nanoparticles for the Electrochemical Oxygen Reduction Reaction

Elizondo-Villarreal N., Rodríguez Ramírez F., Gochi-Ponce Y., Alonso Núñez G., José Yacamán M., University of Texas, Austin, US

Metallic nanoparticles are of great interest because of the modification of properties observed due to size effects, modifying the catalytic, electronic, and optical properties of the monometallic nanoparticles.The polyol method has been reported to produce [...]
