The global carbon balance is broken by anthropogenic activities as humans consume fossil fuels and release a significant amount of CO2 within several hundred years, while the fossil fuel formation takes hundreds of millions of years.  To mitigate the imbalance of global carbon, it is appealing to develop technologies that can efficiently and rapidly convert CO2 into fuels and chemicals without a high excess energy input.  Herein our approach is to couple biomass conversion with CO2 reduction over heterogeneous catalysts under hydrothermal environment.  A variety of biomass feedstocks and metal and metal oxide catalysts were evaluated for the simultaneous biomass partial oxidation and CO2 reduction. In presence of CO2, increase of yields of the carboxylic acids was observed and a high formic acid yield was attributed to CO2 reduction.  The results suggest that CO2 reduction coupling with biomass partial oxidation is an attractive alternative to CO2 capture and sequestration processes.
