Photocatalytic Reduction of Methylene Blue by Formaldehyde in Aqueous Medium in the Presence of Titanium Dioxide Sensitized with 4-[3-(2,6-diphenylpyran-4-ylidene)-prop-1-en-1-yl]-2,6-Diphenylpyranium Tetrafluoroborate

New heterostructures consisting of TiO2 and the dye 4-[3-(2,6-diphenylpyran-4-ylidene)-prop-1-en-1-yl]-2,6-diphenylpyranium tetrafluoroborate were obtained. Their photocatalytic activity in the reduction of methylene blue in relation to the quantitative composition and irradiation conditions was determined. The energy characteristics of possible electronic processes are examined.
