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.

在合成生物柴油燃料中已产生大量副产物甘油，并探索了它们的有效利用方式。甘油的添加有效地增强了从分散TiO ₂光催化剂纳米颗粒的水溶液中光催化H _2的释放。氘标记的实验表明，甘油分子提供了大量的氢原子。H ₂和CO ₂主要在紫外线照射下放出。另一方面，对紫外线照射的系统进行超声处理会增强CO的释放，并且所释放的CO的量取决于超声的强度。H _2的声化学调制/ CO比是生产合成气的一种有前途的方法，合成气是C1化学中的重要原料。
