From: Photo-induced H2 production from a CH3OH-H2O solution at insulator surface
(a) The configuration of reactor used in the experiment; (b) photo-induced H2 production from a CH3OH-H2O solution without photocatalyst under the light irradiation; (c) The concentration dependence of the H2 production from the CH3OH-H2O solution; (d) The pH dependence of the H2 production from the CH3OH-H2O solution, the pH value of solution was adjusted with H2SO4 or NaOH solution (1.0 mol/L). Reaction condition: 500 mL CH3OH-H2O solution, the concentration of CH3OH was 10% in volume in (b,d); 450 W high-pressure Hg lamp; Pure CH3OH (>99.99%) and pure water (18 MΩ H2O, obtained from a Milli-Q water purification system) was used in the experiment.
