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.

When silicone is used to fill joints in surfaces on which vehicles drive, it is advantageous if the silicone contains zinc oxide in the form of tetrapod-shaped crystals.

The present application discloses a method for modifying zinc oxide nanoparticles, comprising following steps: obtaining zinc oxide solution and betaine ligands; mixing the zinc oxide solution and the betaine ligand, keeping a resulting mixed solution reacted under a protective gas atmosphere at a preset temperature, and separating a modified zinc oxide from the resulting mixed solution to obtain a modified zinc oxide. The method for modifying zinc oxide nanoparticles provided in the present application is simple and quick to operate, suitable for industrial production and meets application requirements. And the modified zinc oxide with betaine ligands grafted on the surface has good stability and excellent monodisperse performance, hinders the transmission rate of electrons to a certain extent and improves the recombination efficiency of electrons and holes in the quantum dot light-emitting layer.
