metal co-catalyst for the direct DCC between various arenes and tetrahydrofuran, with concomitant evolution of hydrogen gas. The reactions were done under mild conditions without consuming any oxidising agent or other additional chemicals. This new approach of separating the photocatalyst and the metal catalyst parts allows their independent modification to improve the overall catalytic performance.
脱氢交叉偶联 (
DCC) 是一种通过使用丰富的 C-H 键生成 C-C 键的清洁方法。本研究开发的混合催化剂由 TiO 2光催化剂和 Al 2 O 3负载的 Pd-Au 双
金属催化剂组成,与负载相应
金属助催化剂的常规 TiO 2光催化剂相比,在直接
DCC 之间表现出优异的活性。各种
芳烃和
四氢呋喃,同时放出
氢气。反应在温和的条件下进行,不消耗任何氧化剂或其他额外的
化学品。这种分离光催化剂和
金属催化剂部分的新方法允许它们独立修改以提高整体催化性能。
