Visible light induced photobleaching of methylene blue over melamine-doped TiO2 nanocatalystElectronic supplementary information (ESI) available: Fig. S1. See DOI: 10.1039/c0nr00089b

TiO 2 doping with N -rich melamine produced a stable, active and visible light sensitized nanocatalyst that showed a remarkable efficiency towards the photobleaching of a model compound - methylene blue (MB) in aqueous solution. The photobleaching followed a mixed reaction order kinetics with the distinctive induction and acceleration periods. TiO 2 doping with N -rich melamine produced a stable, active and visible light sentisized nanocatalyst that showed a remarkable efficiency towards the photobleaching of methylene blue in aqueous solution.
