Tiles functionalized with titanium dioxide (TiO2) for the elimination of air pollutants were prepared by the dip-coating process with titanium alkoxide solution. The synthesis of the coating solution consist of a chemical method employing polyethylene glycol (PEG) to obtain better dispersion and adhesion of TiO2 particles onto the ceramic substrates. Nitrogen oxides (NOx). hazardous a... https://www.parisnaturalfoodes.shop/product-category/ubiquinol-coq10/
