We present results from density-functional-theory (DFT) based molecular dynamics simulations of fluid mixtures of carbon dioxide (CO2) and rhenium (Re) metal at pressures up to 45 GPa and a temperature of 4000 K. Covalently-bonded carbon chains form as a result of a redox reaction between CO2 and Re, whereas a pure CO2 fluid is stable against decomposition at the same conditions. Furthermore, these findings have implications in reducing CO2 by pressure-induced redox reactions with transition metals, which may play a role in CO2 destruction and carbon storage as related to possible solutions to the current climate crisis.
