Sunlight began to be used to purify water

Scientists have used photocatalysis, a method of accelerating a chemical reaction through interaction

a special substance - a photocatalyst - withincident light. Some photocatalysts, when absorbed by light, contribute to the oxidation of organic matter, which is used for wastewater treatment, the researchers noted.

Now in industry for similar processesTitanium dioxide TiO2 is used - it is cheap to manufacture, but it reacts to visible light in a relatively narrow range, which significantly reduces its efficiency.

We were able to establish the features of the connections,belonging to the structural type β-pyrochlore, and proposed a new model of the structure, based on which, predicted and synthesized new tellurium-containing compounds. The photocatalysts we have obtained on this basis, on the one hand, meet the criteria put forward for the band structure of the material for carrying out the corresponding reactions, and on the other hand, they are chemically stable in aqueous solutions and organic solvents, which will allow them to be used for a long time.

So the researchers have established which reactions can photocatalyze the resulting materials, which can determine their mutual position of the valence band and the edges of the conduction band.

Scientific team continues detailed researchthe mechanism of the processes of photocatalytic decomposition of organic matter using the already obtained compounds. This will make it possible to understand how it is necessary to modify the compounds, under what conditions and in relation to which processes their efficiency will be maximum.
