Abstract

We have prepared multilayer mesoporous bimetallic (Pt/Pd) alternating films by layer-by-layer (LbL) electrochemical deposition. Because of the high surface area and heterometallic interfacial atomic contacts, enhanced electrocatalytic activity for methanol oxidation reaction is realized. This novel LbL approach allows optimization of the electrocatalytic performance through precise tuning of the thickness of each layer.

摘要

我们通过层层（LbL）电化学沉积法制备了多层介孔双金属（Pt/Pd）交替膜。由于具有高比表面积和异金属界面原子接触，实现了对甲醇氧化反应的增强电催化活性。这种新颖的 LbL 方法可以通过精确调整每层的厚度来优化电催化性能。
