Photocatalytic Decomposition of Indoor Air Pollution Using Dye-Sensitized TiO<sub>2</sub> Induced by Anthocyanin and Ru Complexes

Abstract—This study investigated the characteristics of dye-sensitized TiO2 (DST) using dyes of anthocyanin and Ru complexes, including nature dyes (raspberry, blueberry, cranberry) and artificial dyes (N3 (RuL2(NCS)2•2H2O), N719(C58H86O8N8S2Ru)), prepared by precipitation method following by calcined at muffle furnace and discussed the feasibility of the applications of DST in the removal of volatile organic compounds (VOCs) from the indoor pollution sources using blue, white, red and ultra-violet light emitting diode. UV/Vis absorption spectra, High-resolution scan electron microscopy, Elemental analyses and BET surface area were performed for the characteristic analysis. The results showed that the diluted concentration of dyes affected the decomposition efficiencies (η). In the case of diluted solution of 30 times raw raspberry juice, η was more than 80% and it was higher than that of commercial TiO2. For N3 and N719-sensitized TiO2, their values of η were all in the order of UVLED> BLED> WLED> RLED. Under RLED irradiation, the removal mass of N719DST was 11 times of that of TiO2, showing the optimal special effect on light wavelength. With the irradiation of UVLED, its η increased to 95% with the maximum removal mass of 720 mg/g. Visible light intensity for the photocatalytic reaction is still the major factor.

Index Terms—Dye-sensitized, light emitting diode (LED), anthocyanin, Ru complexes, photodegradation.
