In this paper, a simple method of NaHCO3 reduction to CH3COOH in water with Al powder as a reductant on a commercially available Pd/C catalyst is described that producing CH3COOH with a good yield of 8% from NaHCO3 on a carbon basis at 300 degrees C under hydrothermal conditions. A high adsorption enthalpy of C-1 intermediates on the Pd catalyst may act as an important role in the reduction of NaHCO3 into CH3COOH on Pd/C catalyst. This research provides a simple way to convert the CO2 into a C-2 compound. (C) 2016 Elsevier B.V. All rights reserved.
