摘要
Porous carbons with mesoporous walls (see Figure) are produced by template replication of aggregates of small silica particles, which were themselves templated by a self-assembled lattice of larger monodisperse polystyrene spheres. A direct methanol fuel cell using the new material as a catalyst support shows significantly improved performance due to the combination of high surface area and facile fuel and product diffusion.
