Photo-induced H2 production from a CH3OH-H2O solution using lasers as light source.
(a) The reactor scheme of the two types of irradiation from different directions, side irradiation and top irradiation; (b) Photo-induced H2 production under the irradiation of two different lasers (266 nm and 355 nm); (c) The comparison of photo-induced H2 production via two types of irradiation; (d) Photo-induced H2 production under irradiation by the 355 nm laser at different laser powers. Reaction condition: 100 mL CH3OH-H2O solution (50% CH3OH), irradiation time: 2 h. The system was first vacuumed and saturated with Ar and then irradiated with 266 nm and 355 nm lasers. The laser at 355 nm of a Nd:YAG laser was used as exciting source and the laser at 266 nm comes from the double-frequency of a DPSS 532 Model 200 532 nm laser. The produced H2 was sampled with injector and analyzed with GC.
