About Paper:

Carbon dioxide (CO-) reduction is an important step towards addressing climate change by converting one of the main harmful greenhouse gases into valuable liquid fuels such as formic acid and methanol. One promising approach includes using borohydride (BH,-), a cost-effective, air-stable, and simple hydride source, as a hydride reducing agent. Previous published work in the Grice laboratory has demonstrated that carbon dioxide can be reduced to formate (HCO,°) using sodium borohydride (NaBH,) [1]. Since industrialization, atmospheric carbon dioxide (CO2) levels have risen rapidly. The University Corporation for Atmospheric Research reports current concentrations of 424 ppm and growing at a rate of 2-4 ppm each year. [2,3] In this work, sodium and potassium borohydride were used to study the hydride transfer mechanism and to identify solution conditions that were able to reduce formamide and formate into methanol and urea into formate. Reaction completion and product yield were analyzed using 'H nuclear magnetic resonance (NMR) spectroscopy. Further understanding this direct hydride transfer could provide insight into efficient CO2 reduction and recycling.
