For the first time, this project has achieved the direct in-situ reduction of CO2 to produce formic acid using biomass (glycerol) at a low temperature of 200-300oC, and at the same time, biomass is efficiently oxidized to lactic acid. Glycerol (a by-product of biodiesel production) produces more than 50% lactic acid, and the yield of formic acid from CO2 conversion can reach about 50%. The technical method is simple and does not require a special precious metal catalyst. This technology is unique and belongs to the world's leading level.  

 Climate change and its harm caused by excessive CO2 emissions have become one of the most concerned environmental issues in the world. Our country is a country with coal as the main energy structure and a major emitter of CO2 in the world. The pressure on CO2 emission reduction is particularly severe. Moreover, my country has clearly stated a series of action goals such as reaching a peak in CO2 emissions around 2030 and striving to reach the peak as soon as possible. Therefore, using biomass as energy input to realize the simultaneous resource conversion of CO2 and biomass is undoubtedly huge and immeasurable in society and economy. This technology has not yet been reported and is the world's first.
