be effective electron carriers in the photochemical hydrogen generating system consisting of ascorbic acid as a reproducible electron donor, zinc meso-tetra (4-hydroxysulphophenyl) porphyrin as a photocatalyst. and colloidal platinum. Among them the system using an N-alkyl-4, 4'-bipyridyl, especially the n-hexyl derivative (C6Py+Py), was most effective, where the quantum yield for the hydrogen generation
已发现各种吡啶衍生物是光化学制氢系统中的有效电子载体,该体系由抗坏血酸作为可重现的电子供体,内消旋四(4-羟基磺苯基)锌卟啉锌作为光催化剂。和胶体铂。其中使用N-烷基-4、4'-联吡啶基,尤其是正己基衍生物(C 6 Py + Py)的系统最有效,其中产生氢的量子产率为0.1,理论循环数为的光催化剂达到100,000。讨论了制氢反应的机理。根据许多标准实验,C 6 Py +Py仅在与本发明成分的特定组合中显示有效。
