Abstract
Mesoporous carbon (MC) was prepared from mesoporous silica (SBA-15) via a conventional templating method for use as a Pt?Ru catalyst support in fuel cells. The effect of surface modifications of the carbon support at different pH on the electrochemical activities of the Pt?Ru/MC catalysts was investigated. The Pt?Ru nanoparticle size and loading were dependent on the surface characteristics of the MC. Base-modified MC-supported Pt?Ru showed the smallest average nanoparticle size (3.3 nm) and the highest loading (77%) among the chemically modified MC-supported Pt?Ru catalysts. The electrochemical activity of the catalysts was enhanced when the MC supports were treated with basic or neutral agents rather than by acid modification.
