采用微波辐射法合成了α-四（对羧基苯氧基）酞菁锌（ZnPc COOH），并以3-氨丙基三乙氧基硅烷（APTES）为偶联剂合成了SiO2/ZnPc COOH。采用1HNMR、MS、IR、SEM、TEM、XRD、TG等手段对材料的结构和光学性能进行了表征。红外光谱和热重分析表明，ZnPc COOH与SiO2粒子发生了共价键合。ZnPc COOH和SiO2/ZnPc COOH的单重态氧量子产率分别为0.54和0.21。光催化研究表明，SiO2/ZnPc-COOH纳米粒子具有良好的吸附性、水溶性、光稳定性和促进ZnPc-COOH光催化产生超氧自由基（O2 −·）的能力，从而提高了其光催化活性.研究结果表明，SiO2/ZnPc COOH在光动力学治癌和光降解水污染物方面具有很大的应用潜力。
In this paper, we synthesized α-tetra-(p-carboxyphenoxy) phthalocyanine zinc (ZnPc-COOH) by microwave irradiation method, and SiO 2/ZnPc-COOH by using 3-aminopropyltriethoxysilane (APTES) as the coupling agent. Their structural and optical properties were characterized by 1 HNMR, MS, IR, SEM, TEM, XRD, TG, etc. The synthesized SiO 2/ZnPc-COOH has a porous structure with a 13 nm film of ZnPc-COOH attached on the surface of SiO 2. Infrared spectroscopy and TG analysis demonstrated that ZnPc-COOH has been covalently bonded to SiO 2 particles. The singlet oxygen quantum yields of ZnPc-COOH and SiO 2/ZnPc-COOH are 0.54 and 0.21, respectively. The photocatalytic studies suggested an enhanced activity of SiO 2/ZnPc-COOH nanoparticles due to its good absorption, better water solubility, enhanced photo stability and accelerated photogeneration of superoxide radicals (O 2−•) by ZnPc-COOH. The present work shows that SiO 2/ZnPc-COOH has great potential for application in photodynamic cancer therapy as well as in photo-degradation of water pollutes.
