分级多孔结构材料在催化应用中显示出巨大的潜力。在这项工作中，通过三维（3D）打印和化学去合金化相结合的一种简便的方法被用来合成纳米多孔铜封装微孔金刚石蜂窝结构（NPC@DCS）催化剂。开发的NPC@DCS催化剂被用作非均相类光Fenton催化剂，其催化应用在有机废水的修复举例。实验结果表明，NPC@DCS催化剂对罗丹明B具有良好的降解效果，反应速率为8.24 × 10 ~（-2）min ~（-1），具有良好的稳定性、耐久性、矿化能力和通用性。这项工作不仅表明了所提出的NPC@DCS催化剂在实际应用中用于废水净化的适用性，而且预计将激发3D打印技术和化学合成的结合，以设计具有可调分级微米和纳米孔的高性能金属催化剂用于功能应用。
Hierarchically porous-structured materials show tremendous potential for catalytic applications. In this work, a facile method through the combination of three-dimensional (3D) printing and chemical dealloying was employed to synthesize a nanoporous-copper-encapsulating microporous-diamond-cellular-structure (NPC@DCS) catalyst. The developed NPC@DCS catalyst was utilized as a heterogeneous photo-Fenton-like catalyst where its catalytic applications in the remediation of organic wastewater were exemplified. The experimental results demonstrated that the NPC@DCS catalyst possessed a remarkable degradation efficiency in the removal of rhodamine B with a reaction rate of 8.24 x 10(-2) min(-1) and displayed attractive stability, durability, mineralization capability, and versatility. This work not only manifests the applicability of the proposed NPC@DCS catalyst for wastewater purification in practical applications but also is anticipated to inspire the incorporation of the 3D printing technology and chemical synthesis to design high-performance metal catalysts with tunable hierarchical micro- and nanopores for functional applications.
