摘要：

A facile and reliable method has been developed to synthesize single crystalline Pt nanotubes (S-PtNTs) with Pt (111) dominated facets. It is verified that the Pt (111) dominated facets in S-PtNTs play a crucial role in improving the catalytic stability for the methanol oxidation reaction (MOR) and the oxygen reduction reaction (ORR).
