Recently, great attention has been focused on hydrogen as a clean and renewable potential energy vector. In the present study, a functional system designed for photocatalytic hydrogen evolution from water was developed and analyzed. Essays consisted of cylindrical borosilicate reactor with 750 mL suspension under nitrogen atmosphere, 100 mg L-1 of 0.5% m/m Pt-loaded TiO2 (P25, M02 or M19) using hexachloroplatinic acid as cocatalyst (Pt) precursor and aqueous solution of eléctron donor as sacrificial reagent (methanol, paracetamol or sodium lignosulfonate) at different concentrations. The pH of the suspension was adjusted using NaOH 0.1 mol L-1 or HCl 0.1 mol L-1 solutions previously prepared. The obtained system was maintaned under controll...
