Abstract: Methods for embedding photocatalytic titanium dioxide in concrete surfaces to reduce pollutants via photocatalytic reactions are provided herein. One method includes mixing a solvent compound with an anatase titanium dioxide (TiO2) photocatalyst, applying an amount of concrete treatment compound to an upper surface of the concrete, the concrete treatment compound comprising a mixture of a liquid carrier compound with the anatase titanium dioxide (TiO2) photocatalyst.
Abstract: The manufacturing method of titanium dioxide solution includes: mixing choline chloride, urea, boric acid, and titanium tetrachloride to form a first solution, wherein a molar concentration ratio of choline chloride to urea is 1:2, a molar concentration of titanium tetrachloride is 0.2 M to 0.4 M, and weight/volume of boric acid is 5 g/300 ml to 15 g/300 ml; and heating the first solute ion to form a second solution, wherein the second solution contains carbon/nitrogen doped titanium dioxide. In the manufacturing method of the present disclosure, the deep eutectic solution formed by choline chloride and urea may be used as a solvent, and may also be used as a carbon source and/or a nitrogen source. Therefore, titanium dioxide may be doped with carbon and/or nitrogen during the formation process.
Abstract: A biopolymer film is provided that comprises a combination of crystalline nano cellulose (CNC)/esterified crystalline nano cellulose (ECNC) reinforced with chitosan.

Abstract: The invention discloses a nitrogen-doped mesoporous carbon-coated Titanium dioxide composite photocatalyst, a preparation method and use thereof. The preparation method comprises the steps of: dissolving an organic ligand and Ti(OC3H7)4 in a mixture of methanol and DMF at a certain ratio, performing a hydrothermal reaction, centrifuging and drying to obtain a Titanium-based metal organic framework (Ti-MOF); pyrolyzing the obtained Ti-MOF under an inert atmosphere, and oxidizing the same for etching to obtain a nitrogen-doped mesoporous carbon-coated Titanium dioxide composite photocatalyst. The obtained composite photocatalyst not only facilitates the adsorption, enrichment and mass transfer of low concentration VOCs, but also efficiently degrades VOCs under sunlight. It has high degradation activity and stability when performing photocatalytic removal of VOCs in the presence of visible light, is simple in synthesis, low in preparation cost, and has strong potential for the use in environmental protection.
