Surface activation is considered to regulate the electronic structures of materials for enhancing catalytic capability. Herein, we report a controllable strategy for constructing three-dimensional micro-nanoporous copper catalysts with high reactivity and activity for the degradation reaction of organic pollutants. Various micro-nanoporous structures and formation processes by chemical selective dealloying of Cu-based metallic glasses are evaluated due to the surface modification. The porous catalysts exhibit superior catalytic performance, attributing to the catalytic mechanisms related to the superior surface activity of nanoscale copper composites and the strong oxidizing capability of activated radicals. These findings will provide a promising synthesis approach for three-dimensional micro-nanoporous catalysts for many chemical reactions.
表面活化被认为可调节材料的电子结构以增强催化能力。在此，我们报告了一种可控策略，用于构建对有机污染物降解反应具有高反应性和活性的三维微纳米多孔铜催化剂。由于表面改性，通过对铜基金属玻璃进行化学选择性脱合金化来评估各种微纳米多孔结构及其形成过程。这些多孔催化剂表现出优异的催化性能，这归因于与纳米级铜复合材料的卓越表面活性以及活性自由基的强氧化能力相关的催化机制。这些发现将为许多化学反应的三维微纳米多孔催化剂提供一种有前景的合成方法。
