RUDN chemists found a new way to neutralize damaging phenol releases using the nanoparticles of titanate salts. Besides titanium and oxygen, they contain the atoms of metals (e.g. magnesium, chrome, or cobalt) that can accept and release electrons in the phenols oxidation reaction under the influence of light. As a result of oxidation, phenols turn into water and carbon dioxide. The authors of the work suggested synthesizing these nanoparticles on the basis of titanium butoxide (organic titanium oxide) and metal salts in the presence of an organic solvent.

"Photocatalysts are of specific interest for us as water purifying agents. They accelerate the disintegration of dangerous substances under light, including visible light. The end products of such a reaction are water and carbon dioxide that are completely save for the environment. In our work, we've described a new method of synthesizing the nanoparticles that oxidize phenols under the influence of light, quickly and at relatively low temperatures," said Yahua Absalan, a post-graduate of the Department of General Chemistry at the Faculty of Physics, Mathematics, and Natural Sciences, RUDN.
