A photosensitizer based on a ruthenium complex of a bisamide-polypyridyl ligand gives rise to a large improvement in photocatalytic stability, rate of activity, and efficiency in photocatalytic H production compared to [Ru(bpy) ] (bpy=2,2'-bpyridine). The bisamide ruthenium polypyridyl complex combined with a cobaltoxime-based photocatalyst was found to be highly efficient under blue-light (turnover number (TON)=7800) and green-light irradiation (TON=7200) whereas [Ru(bpy) ] was significantly less effective with a TON of 2600 and 1100, respectively. The greatest improvement was under red-light-emitting diodes, with bisamide ruthenium polypyridyl complex and cobaltoxime exhibiting a TON of 4200 compared to [Ru(bpy) ] and cobaltoxime at a TON of only 71.
一种基于双酰胺-多吡啶配体的钌配合物的光催化剂，与[Ru(bpy) ]（bpy=2,2'-联吡啶）相比，在光催化产氢的光催化稳定性、活性速率和效率方面有了很大的提高。双酰胺钌多吡啶配合物与基于钴肟的光催化剂结合，在蓝光（转化率（TON）=7800）和绿光照射下被发现具有很高的效率，而[Ru(bpy) ]的效率则显著较低，分别为 TON=2600 和 1100。在红色发光二极管下，双酰胺钌多吡啶配合物和钴肟的 TON 达到了 4200，而[Ru(bpy) ]和钴肟的 TON 仅为 71。
