Plasmonic nanoparticle-involved materials play an essential role in the field of photothermal conversion. Herein, we report the application of photothermal heterogeneous catalysts consisting of gold nanoparticles decorated on defect-rich h-BN sheets (Au/h-BN) for the photocatalytic synthesis of α-cyanoacrylonitriles under mild conditions. It has been demonstrated the-NH groups present in the defect-rich h-BN act as the catalytically active sites, while plasmonic heating from the gold nanoparticles can drive the reaction by providing local heat. Au/h-BN catalyst can work for a broad substrate scope in the synthesis of α-cyanoacrylonitriles, and a plausible -NH group-involved reaction mechanism has been proposed. This work may open up new avenues in photothermal catalysis by combining plasmonic materials and catalytic sites in one system.
等离子体纳米粒子参与的材料在光热转换领域起着至关重要的作用。在此，我们报道了由负载在富含缺陷的h-BN片材上的金纳米粒子组成的光热多相催化剂（Au/h-BN）在温和条件下用于光催化合成α-氰基丙烯腈的应用。已经证明，富含缺陷的h-BN中存在的-NH基团充当催化活性位点，而来自金纳米粒子的等离子体加热可以通过提供局部热量来驱动反应。Au/h-BN催化剂在α-氰基丙烯腈的合成中对广泛的底物范围有效，并且已经提出了一种合理的涉及-NH基团的反应机理。这项工作可能通过在一个系统中结合等离子体材料和催化位点为光热催化开辟新途径。
