Climate change is a global environmental concern. A major contribution to climate change comes from excessive burning of fossil fuels. They produce carbon dioxide (CO2), a greenhouse gas responsible for global warming. In this light, governments globally are framing policies to curb such carbon emissions. However, merely curbing carbon emissions may not be enough. Managing the generated carbon dioxide is also necessary.
On this front, scientists have suggested chemically converting CO2 into value-added compounds, such as methanol and formic acid (HCOOH). Producing the latter requires a source of hydride ion (H-), which is equivalent to one proton and two electrons. For instance, the nicotinamide adenine dinucleotide (NAD+/NADH) reduction-oxidation couple is a hydride (H-) generator and reservoir in biological systems.
Against this backdrop, a group of researchers led by Professor Hitoshi Tamiaki from Ritsumeikan University, Japan, have now developed a novel chemical method that reduces CO2 to HCOOH using NAD+/NADH-like ruthenium complexes. Their work was published in the journal ChemSusChem on 13 January 2023New window.
