Dehydrogenative cross-coupling (DCC) is a clean methodology to make C-C bonds by using abundant C-H bonds. The blended catalyst, developed in this study, consists of a TiO photocatalyst and an AlO supported Pd-Au bimetallic catalyst and shows superior activity to the conventional TiO photocatalyst loaded with the corresponding 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）是一种利用丰富的C-H键来形成C-C键的绿色方法。本研究开发的复合催化剂由TiO光催化剂和AlO负载的Pd-Au双金属催化剂组成，对于各种芳烃与四氢呋喃之间的直接DCC反应，该复合催化剂表现出优于负载相应金属助催化剂的传统TiO光催化剂的活性，同时伴有氢气放出。反应在温和条件下进行，无需消耗任何氧化剂或其他额外化学品。这种将光催化剂和金属催化剂部分分离的新方法允许对它们进行独立改性，以提高整体催化性能。
