最近报导:有一种铑络合物能光解水,它的分子构型为风车状,是含有四个1,3-二异氰基丙烷配位体的铑络合物二聚体。这个铑络合物的特征吸收波长为553nm,经此波长光照射后它变为还原型的蓝色络合物,再用546nm光照射该蓝色铑络合物,即转变为一种黄色产物,同时放出氢。此光化学反应速度快而可逆,但自发的逆反应是慢的,因此可以作为太阳能光解水制氢的光解催化剂。目前还存在一些问题。例如量子产率仅0.4％, Recently it has been reported that there is a rhodium complex capable of photolysis of water and its molecular configuration is a pinwheel, a rhodium complex dimer containing four 1,3-diisocyanatodiphn ligands. The characteristic absorption wavelength of this rhodium complex is 553 nm, after which it becomes a reduced blue complex upon irradiation with light, and then the blue rhodium complex is irradiated with 546 nm light, that is, into a yellow product , While releasing hydrogen. The photochemical reaction is fast and reversible, but the spontaneous reverse reaction is slow, so it can be used as a solar photolysis of hydrogen photolysis catalyst. There are still some problems. For example, the quantum yield is only 0.4%
