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.

Abstract: The method for synthesizing zinc oxide nanoroses is a green, fast, and cost-effective approach for the growth of ZnO nanoroses in which a sheet of vertically aligned and interconnected sheet of ZnO nanospheres are grown on a titanium buffer layer coated on a silicon substrate, the nanospheres mimicking a rose-like structure. According to the method, a film of titanium is first deposited on a Si/SiO2 substrate by an e-beam evaporation method. Then, the titanium film coated substrate is suspended upside down in a solution of zinc nitrate (0.011 M-0.055M) in an aqueous solution of hexamethylenetetramine (0.011 M-0.055M) and heated to 50-100° C. with vigorous stirring for 60-180 min. The resulting ZnO nanoroses are washed with de-ionized water and air-dried for 12-24 hours. The ZnO nanoroses are suitable for use for various device applications in electronics and in biomedical systems.

Abstract: High surface area 3D mesoporous carbon nanocomposites can be derived from Zn dust and PET bottle mixed waste with a high surface area. Simultaneous transformation of Zn metal into ZnO nanoparticles and PET bottle waste to porous carbon materials can be achieved by thermal treatment at preferably 600 to 800° C., and reaction times of from 15 to 60 minutes, after optionally de-aerating the reaction mixtures with N2 gas. The waste-based carbon materials can have surface areas of 650 to 725 m2/g, e.g., 684.5 m2/g and pore size distributions of 12 to 18 nm. The carbon materials may have 3D porous dense layers with a gradient pore structure, which may have enhanced photocatalytic performance for degrading, e.g., organic dyes, such as methylene blue and malachite green. Sustainable methods make ZnO-mesoporous carbon materials from waste for applications including photocatalysis, upcycling mixed waste materials.

Abstract: A cleaning sachet for removing carbon deposit and rust on a gun element, and a cleaning method thereof, uses cleaning powder that includes aluminum oxide making up 75.000% to 99.989% by weight of the cleaning powder, zinc peroxide making up 0.010% to 9.000% by weight of the cleaning powder, and nano zinc oxide making up 0.001% to 6.000% by weight of the cleaning powder. A user can lay the cleaning sachet on a carbon-deposited and/or rusting area of the gun element before or after moistening the cleaning sachet with a lubricating oil, and then wipe the carbon-deposited and/or rusting area with the cleaning sachet after waiting a period of time. Therefore, the colloidal solution formed by mixing the lubricating oil and the cleaning powder and released out of the cleaning sachet can remove the carbon deposit and/or rust on the surface of the gun element.
