| Summary: | A Hubbard parameter of 7 eV correctly describes the oxidation enthalpy and band gap of CuO.Methylglyoxal can be chemisorbed and activated over the CuO(111) surface to finally achieve lactic acid. A study of the adsorption modes of glycerol and lactic acid is needed before starting the reactionmechanism. A comparison between CuO and Cu2O could help to understand the high conversion andselectivity of glycerol towards lactic acid. |
