Resumen:
Recently, we tested the capability of hydroxoaluminium-tricarboxymonoamidephthalocyanine (AlTCPc) adsorbed on TiO2 for the photocatalytic reduction of Cr(VI) under visible irradiation in the presence of 4-chlorophenol as sacrificial electron donor (*). It was demonstrated that a very rapid reduction to Cr(III) is possible in spite of the aggregation of AlTCPc on the surface of TiO2. Moreover, an apparent independence of the photocatalytic activity on dye loading was observed. In order to elucidate the role of aggregates in charge injection, the photoelectric behavior of AlTCPc adsorbed on a TiO2 electrode is studied in this work.
