以铁、镍、锌金属卟啉为光敏剂光照分解水产氢的研究

以铁、镍、锌金属卟啉为光敏剂光照分解水产氢的研究 STUDY ON THE PHOTODISSOCIATION OF WATER INTO HYDROGEN WITH Fe, Ni, Zn METALLO PORPHYRINS AS PHOTOSENSIZERS 季立才 first-author 吴萱阶 黄素秋 李如松 在金属吓啉/TEOA/2,2′-bpy/K 2 PtCl 6 体系中,研究了用四苯基金属吓啉（M-TPP）-Fe-P、Ni-P、Zn-P和八乙基金属吓啉（M-OEP）-Ni-O-A、Zn-O-A、Zn-O-B为光敏剂,光照分解水产氢。考察了产氢量与pH、反应时间、不同光敏剂及体系中其他组份的关系。比较了M-OEP型光敏剂Zn-O-A或Zn-O-B与M-TPP型光敏剂Zn-P的产氢量与光敏化性能,结果表明,Zn-O-A和Zn-O-B比Zn-P好。 In the system of metalloporphyrin/TEOA/2, 2’-bpy/K 2 PtCl 6 , the photodissociation of water into hydrogen has been studied with metallotetraphcnylporphyrins（M-TPP）-Fe-P、Ni-P、Zn-P and metallooctaethylporphyrins（M-OEP）-Ni-O-A、Zn-O-A、Zn-O-B as photosensitizers. The relationship between quantities of hydrogen produced and pH, reaction times, different photosensitizers and other components of the system was inspected The photosensitive fuctions and quantites of produced hydrogen of photosensitizer M-OEP（Zn-O-A or Zn-O-B）and M-TPP（Zn-P）has been compered. The results indicate that Zn-O-A and Zn-O-B are better than Zn-P 1986-03-01 2021-04-01 3
