A factorial design at two levels and four factors has been carried out in order to investigate the potential for hydrogen generation using Eosin Y-sensitized TiO2/Pt catalyst under visible solar light in presence of triethanolamine (TEOA) as electron donor. The solution pH was found to be a significant parameter, and was maintained at pH 7.0 throughout the investigation. Visible light irradiation time (I-time) showed highest positive effect on hydrogen generation followed by initial Eosin Y concentration (for dye-sensitization) and the TEOA concentration while Pt content (wt %) in TiO2 showed negative effect toward hydrogen generation. Experimental data were analyzed using both “Pareto analysis” as well as conventional regression analysis techniques. A regression function is proposed that satisfactorily predicts hydrogen generation.
► This article deals with sacrificial H2 generation from H2O with dye-sensitized photocatalyst.
► Factorial design analysis provides a quantitative appraisal that influence the performance.
► Solution pH is a significant parameter as it affects the stability of dye-sensitized TiO2/Pt.
► The w% Pt content in TiO2 has a negative effect.
► Experimental data were analyzed using both “Pareto analysis” and regression techniques.
