摘要：
Ordered mesoporous carbon (OMC) was synthesized using low-polymerization-degree phenolic resin as carbon precursor, and triblock copolymer F127 (M-w=12 600, PEO106PPO70PEO106) as a structure-directing agent by microwave irradiation heating method. XRD, TEM and low temperature nitrogen adsorption results show that the as-prepared OMC possess highly ordered mesoporous structure with BET Surface area of 614 m(2).g(-1) and pore volume of 0.47 cm(3) The OMC surface modification with respective NaBH4 and colloid palladium solution results in activated and deposited Pd particles on the surface. Due to the enhanced conductivity and hydrophilicity of carbon surface, well-dispersed and high-loading Pt nanoparticles were obtained, as evidenced by the increase of electrochemically active surface area from 4 to 29 m(2).g(-1).
