摘要
采用四羧基锌酞菁(Zn-taPc)制备得到一种强负载型可见光敏剂,并对其做了紫外-可见漫反射光谱的表征.考察了苯酚的可见光降解反应,在pH=12和负载量0.4%条件下,苯酚2.5 h的降解率达到95.67%.进一步淬灭实验证明,单重态氧是苯酚降解的活性氧化物种.
Zinc tetracarboxyphthalocyanines（Zn-taPc） were used to prepare strong supported photosensitizes,which were characterized by the UV-vis diffuse reflection spectrum.The reaction of phenol decomposition under visible light irradiation in the presence of Zn-taPc was investigated,while the phenol degradation rate within 2.5 h reached 95.67% at pH 12 at 0.4% loading.Further quenching experiment indicated that singlet oxygen radicals were the main reactive oxidizing species in phenol degradation.
