摘要

Nanoporous Pt hollow nanostructures with octahedral and hexagonal frame-like morphologies were prepared by a novel one-pot self-templating route with no assistance from a preformed template or shape-directing agent. The hexagonal frame-like Pt hollow structures exhibited significantly enhanced catalytic activity toward CO oxidation reaction compared to the octahedral Pt hollow nanostructures due to the higher oxidation state of Pt.
