Hydrogen photoproduction from bio-derived alcohols in an optical fiber honeycomb reactor loaded with Au/TiO2
Rights accessRestricted access - publisher's policy
Cordierite honeycombs loaded with 1 wt.% Au/TiO2 have been used in an optical fiber photoreactor illuminated with UV LEDs to produce hydrogen at 298 K from aqueous methanol, ethanol, glycerol, bio-ethanol, and bio-glycerol in liquid phase. The amount of alcohol has been varied between 1% and 100%. Under the same photoreaction conditions, the amount of hydrogen produced follows the trend: methanol similar to ethanol similar to glycerol > bio-ethanol >> bio-glycerol. Hydrogen photogeneration is significantly enhanced (4-5-fold increase) in the optical fiber honeycomb photoreactor with respect to a conventional slurry photoreactor. (C) 2014 Elsevier B.V.
