中文摘要：

四氨基钴酞菁作为一种有前途的可见光催化剂,可光敏化为三线态,与溶液中的O2反应产生活性氧.实验考察了反应过程中的光照时间、光敏剂质量、光照强度和pH等4个因素对活性氧产生的影响,同时确定了一种简单可行的检测方法：活性氧与卡巴肼（DPCI）反应,生成卡巴腙（DPCO）,以苯-四氯化碳萃取,在563 nm处测其吸光度,从而表示出活性氧的相对产量.实验优化了四氨基钴酞菁催化产生活性氧的条件：于50 mL的溶液中,光照时间为25 min,光敏剂质量为5 mg,光照强度为60 W,pH值为4.同时证明了在反应体系中生成了自由基和单线态氧等活性氧,并且对光催化产生活性氧的机理进行了探讨.

英文摘要：

As a kind of promising catalyst with visible light,tetraamino cobalt phthalocyanine can be semsitized triplet state.And it can react with O2 in solution to produce reactive oxygen species.This experiment studies the influences on reactive oxygen by the four factors of reaction time,quality of photosensitizer,light intensity and pH in the reaction process.Meanwhile,this experiment ensures a simple and feasible test method： When the reactive oxygen species reacts with kappa hydrazine（DPCI）,kappa hydrazone（DPCO） will be generated and the relative production of reactive oxygen will be expressed when measuring the absorbance at 563 nm by using benzene-carbon tetrachloride extraction.This experiment optimizes the conditions in which the tetraamino cobalt phthalocyanine serves as a catalyst to produce reactive oxygen condition： 50 mL solution with 25 min illumination time and 5 mg photosensitizer quality,the light intensity is 60 W and the pH value is 4.This experiment also proves that singlet oxygen and other reactive oxygen species are generated in the reaction.The mechanisms of reactive oxygen species production under light catalytic are discussed.
