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 Ngas. The waste-based carbon materials can have surface areas of 650 to 725 m/g, e.g., 684.5 m/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.

Mesoporous zinc oxide graphite composite

An efficient photocatalyst nanocomposite comprising reduced graphene oxide, noble metal, and a metal oxide prepared by a one-step method that utilizes date seed extract as a reducing and nanoparticle determining size agent. The photocatalyst of the invention is a more effective sunlight photocatalyst than that prepared by traditional method in the photo decomposition of organic compounds in contaminated water.

A method of removing one or more antibiotics from a dairy product, the method involve passing the dairy product comprising an antibiotic in a first amount through a bulk comprising, relative to a total bulk weight, at least 75 wt. % of titanium oxide nanostructures, to provide the dairy product comprising the antibiotic in a second, lesser amount, wherein the nanostructures have lengths at least two-fold in excess of their width and height. Bulk materials useful in this or related methods or applications may have loosely tangled, noodle-like morphologies on sub-100 nm scale, and need not employ graphene and/or polymeric support networks in columns, generally having only titanium oxides without silicon or iron oxides.
