9,10-二氰基蒽光敏分解水制氢反应的研究

A STUDY OF 9,10-DICYANOANTHRACENE PHOTOSENSITIZED SPLITTING WATER TO GENERATE MOLECULAR HYDROGEN

本文以9、10-二氰基蒽(DCA)为敏化剂,测定了用胺类,单烯类及取代苯类化合物为电子给体时光敏还原甲基紫精(MV^(2+))的量子产率。用三乙醇胺(TEOA)为电子给体,探索了胶体铂存在下DCA光敏分解水制氩的反应条件并研究了用甲苯、对二甲苯为电子给体时DCA光解水制氢的反应。结果表明以DCA为敏化剂时许多化合物(E^(ox)<2V)均可作为电子给体,在制氢的同时还有可能合成有用化合物等优点。

In this paper,the quantum yield of 9,10-dicyanoanthracene sensitized photoreduction of methyl viologen was measured.Amines,olefins and substituted benzenes were used as electron donor.Reaction conditions of splitting water to generate molecular hydrogen were discussed.The reaction was studied with toluene and p-xylene'as donors.A wide range of electron donor compounds can be used and some useful compounds may be synthesized simutaneously with hydrogen generation.
