Abstract

Highly ordered fully interconnected hierarchical macroporous carbons with uniform mesoporous walls were fabricated by template nanocasting of aggregates of the small silica particles as molds, which were also templated by self-assembled ordered lattice of larger monodisperse polystyrene spheres. The hierarchical porosity can be easily manipulated by controlling the sizes of the polystyrene and silica particles. Due to unique structural properties of the porous carbon with fully interconnected ordered uniform hierarchical porosity and high surface area, the carbon could play as an excellent catalyst support, resulting in great improvement for fuel oxidation activity in PEM fuel cell.
