Dehydrogenation of Glycerol for CO2 Reduction in One-Pot Production of Lactic Acid and Formic Acid with Ru-MACHO

Graphical Ru-MACHO catalysts can simultaneously satisfy parallel reactions because of having the outstanding ability to dehydrogenate glycerol into LA and hydrogenate CO 2 into FA under conditions of 200 °C and 48 h. Dehydrogenation of glycerol for CO 2 reduction can simultaneously produce lactic acid (LA) and formic acid (FA) products with high added value, greatly improving the atomic economy and the actual benefits. We report that Ru-MACHO (regR) as a catalyst can satisfy the requirements of parallel reaction at the same time. The designed experiment confirms that under the conditions of 200 °C and 48 h, 3 mg Ru-MACHO (regR) catalyst can obtain FA and LA yields of 40 % and 45 %, respectively. The possible reaction path of glycerol dehydrogenation for CO 2 reduction is confirmed by the isotopic tracer technique and nuclear magnetic resonance analysis.
