Novel Pt/Ni multi-layered nanotube arrays (MLNTAs) are synthesized by template-assisted layer-by-layer electrodeposition. The unique multi-layered structures in nanotube walls provide a new method to study the effects of heterointerfaces and structures on methanol electrooxidation. For the fabricated Pt/Ni MLNTAs, especially Ni@Pt@Ni@Pt NTAs, we observed obvious enhancements in the catalytic activity and durability compared with the monometallic Pt nanotube arrays (NTAs) and many Pt-based catalysts reported in the literature studies. Our synthesis approach presents a strategy to broaden the heterointerfacial and structural effects for harnessing the true catalytic potential of Pt-based electrocatalysts and may lead to wide applications for energy conversion and storage.
