摘要：

One-dimensional multimetallic nanotubes with meso-porous walls are promising electrocatalysts for fuel cells on account of their distinct morphology and tunable composition. In the present work, we adopt a micelle-assisted galvanic replacement strategy to synthesize one-dimensional mesoporous AgPdPt nanotubes (AgPdPt MNTs) with uniform morphology and size in aqueous solution. On account of their distinct mesoporous nanotube structure and synergistic effect among different metals, the as-synthesized trimetallic AgPdPt MNTs exhibit enhanced catalytic performance toward the oxygen reduction reaction. This work offers a feasible method to design one-dimensional mesoporous nanotubes with tunable composition for various promising applications.
