Carbon cryogel as support of platinum nano-sized electrocatalyst for the hydrogen oxidation reaction
(Electrochimica Acta, 2006)
The kinetics of hydrogen oxidation reaction was studied in perchloric acid solution on carbon-supported Pt nanoparticles using the rotating disk electrode technique. Carbon cryogel and commercial carbon black. Vulcan XC-72 ...
Incorporation of Pt, Ru and Pt-Ru nanoparticles into ordered mesoporous carbons for efficient oxygen reduction reaction in alkaline media
(Electrochimica Acta, 2015)
Ordered mesoporous carbon, volume-doped up to 3w.% with Pt, Ru and Pt-Ru nanoparticles was synthesized by evaporation-induced self-assembly method, under acidic conditions. The content of incorporated metal was determined ...
Ni-Sn coatings as cathodes for hydrogen evolution in alkaline solutions
