Glycerol has recently been considered as a new platform to produce C3 chemicals. As new pathway to produce acrylic acid, utilization of glycerol have attracted attention. In this work, glycerol was efficiently converted to 87 % yield of acrylic acid by two step pathway; glycerol was converted to allyl alcohol by formic acid-mediated deoxydehydration (DODH), then the allyl alcohol was oxidized into acrylic acid in a basic aqueous solution using Au/CeO2 catalysts. The Au/CeO2 catalysts enable the highly selective production of acrylic acid from glycerol-derived allyl alcohol. Different shapes of CeO2 such as rods, octahedra, and cubes were prepared, and gold was deposited on the CeO2 by deposition precipitation method. Gold on octahedra CeO2 catalysts showed high yield of acrylic acid with stability. |
