Au@Pd core-shell nanobricks (CNBs) with concave surfaces and Pd shells with a thickness of approximately 5 nm were synthesized by co-reduction of HAuCl4 and H2 PdCl4 in the presence of Au seeds and Ag ions. These as-synthesized concave CNBs exhibit significantly enhanced catalytic activity for the electrooxidation of ethanol in alkaline media compared to the commercially-used Pd black. The improved performance of the Au@Pd CNBs can be attributed to the exposed stepped surfaces, high-index facets, and the synergistic effects of the core and shell metals.
Au@Pd 核壳纳米砖（CNBs）具有凹面和厚度约为 5nm 的 Pd 壳，通过在 Au 种子和 Ag 离子存在下共还原 HAuCl4 和 H2PdCl4 合成。与商业 Pd 黑相比，这些合成的凹面 CNBs 在碱性介质中对乙醇的电氧化表现出显著增强的催化活性。Au@Pd CNBs 的性能提高归因于暴露的阶梯表面、高指数晶面以及核和壳金属的协同效应。
