封面显示了含氮喹啉环（Qns）在含金属助催化剂改性的二氧化钛光催化剂的酒精悬浮液中的无氢加氢反应。在他们的研究文章中，H. Kominami和同事们表明，氢化作用与h2在助催化剂上的演化相竞争，使用Rh助催化剂可以产生较大的1,2,3,4 -四氢喹啉（THQn）收率和更大的h2收率。相比之下，使用便宜的Cu助催化剂，THQn产率相对较高，H 2的生成受到极大抑制，并且在稍微升高的温度下，氢化反应大大加快。研究了cu - tio2在太阳光照下的加氢作用，以及cu - tio2的可扩展性和可重复使用性。更多信息可以在H. Kominami及其同事的研究文章中找到。
The Front Cover shows hydrogen-free hydrogenation of a nitrogen-containing ring of quinolines (Qns) in an alcoholic suspension of a TiO 2 photocatalyst modified with metal cocatalysts. In their Research Article, H. Kominami and co-workers show that hydrogenation competed with H 2 evolution over the cocatalyst, and the use of a Rh cocatalyst resulted in a large 1, 2, 3, 4-tetrahydroquinoline (THQn) yield and a much larger H 2 yield. In contrast, the use of an inexpensive Cu cocatalyst resulted in a relatively large THQn yield with greatly suppressed evolution of H 2, and the hydrogenation was greatly accelerated at slightly elevated temperatures. Hydrogenation over Cu-TiO 2 under solar light was investigated in addition to the expandability and reusability of Cu-TiO 2. More information can be found in the Research Article by H. Kominami and co-workers.
