Large amount of glycerol has been generated as a byproduct in the synthesis of biodiesel fuel and their effective utilization ways have been explored. Addition of glycerol effectively enhanced photocatalytic H2 evolution from aqueous solution dispersing TiO2 photocatalyst nanoparticles. The deuterium labeled experiments clarified that noticeable amount of hydrogen atoms are supplied from glycerol molecules. H2 and CO2 were mainly evolved under UV illumination. On the other hand, sonication to the UV-illuminated system enhanced the CO evolution and the amount of the evolved CO depended upon the intensity of the ultrasound. Sonochemical modulation of H2/CO ratio is a promising approach to produce syngas, which is an important raw material in C1 chemistry.
