Stepwise synthesis, characterization, and electrochemical properties of ordered mesoporous carbons containing well-dispersed Pt nanoparticles using a functionalized template route

A stepwise method is described for the accurately controlled growth of Pt nanoparticles supported on ordered mesoporous carbons (Pt–OMC) by the nanocasting of carbon and metal precursors in the pore channels of mesoporous silicas functionalized with Si–H groups. Results obtained from N 2 adsorption/...
