Abstract
A composite nanomaterial of ZnO impregnated by, e.g., a green copper phthalocyanine compound (CuPc) can be an efficient solar light photocatalyst for water remediation. The composite may include hollow shell microspheres and hollow nanospheres of CuPc-ZnO. CuPc may function as a templating and/or structure modifying agent, e.g., for forming hollow microspheres and/or nanospheres of ZnO particles. The composite can photocatalyze the degradation of organic pollutants such as crystal violet (CV) and 2,4-dichlorophenoxyacetic acid as well as microbes in water under solar light irradiation. The ZnO—CuPc composite can be stable and recyclable under solar irradiation.
Claims14
A method of synthesizing a composite including hollow micro (hemi) spheres and/or nanospheres, comprising:
- mixing a zinc compound with a solvent mixture of ethanol/diethylene glycol to form a solution, then mixing the solution with a copper phthalocyanine compound to form a reaction mixture, wherein the solution and the reaction mixture comprise the same solvent mixture;
- and
- heating the reaction mixture at a temperature in a range of 100 to 200° C. for a treatment time in a range of 10 to 30 hours to form the composite,
- wherein a molar ratio of the zinc compound to the copper phthalocyanine compound is in a range 3:1 to 1:3.
