考察了水-三乙醇胺-氯化铑-2,2’-联吡啶-铂体系受紫外光照时的行为。所研究的体系既能发生催化产氢反应,也可以使氢与氧结合成水。氧对产氢过程有强烈的抑制作用。用重水代替上述体系中的水时,光照时主要放出D_2。 在几种不同波长范围的照射条件下,比较了钌和铑的络合物作为光敏剂时的不同反应特性,讨论了它们的差别。此外,用带多种光敏剂的催化体系来提高太阳能储存效率是可能的。
The behavior of water-triethanolamine-rhodium chloride-2,2’-bipyridyl-platinum system under ultraviolet illumination was investigated. The system studied can not only catalyze the hydrogen production reaction, but also make hydrogen and oxygen combine into water. Oxygen has a strong inhibitory effect on hydrogen production. With heavy water instead of water in the above system, the main light emitted D_2. The different reaction characteristics of ruthenium and rhodium complexes as photosensitizers were compared under several illumination conditions with different wavelength range and their differences were discussed. In addition, it is possible to increase the solar storage efficiency with catalytic systems with multiple photosensitizers.
