Publications and Research
TiO2 was sensitized with a porphyrin, Tetra(4-carboxyphenyl) porphyrin(TCPP) and used as photocatalyst under visible light for degradation of aqueous solutions of methylene blue (MB) dye. The quantification of the degradation of MB was assessed by UV-Vis spectroscopy. The results of this procedure showed the decrease in concentration of MB over time when reaction is exposed to visible light. The TiO2-TCPP complex was tested as well for the recovery of metals from the AgNO3 aqueous solution. The reduction of silver cations to silver metal was observed through formation of black precipitate.
