Selective photoelectrochemical oxidation of glycerol to high value-added dihydroxyacetone

It is highly profitable to transform glycerol – the main by-product from biodiesel production to high value-added chemicals. In this work, we develop a photoelectrochemical system based on nanoporous BiVO(4) for selective oxidation of glycerol to 1,3-dihydroxyacetone – one of the most valuable deriv...

description It is highly profitable to transform glycerol – the main by-product from biodiesel production to high value-added chemicals. In this work, we develop a photoelectrochemical system based on nanoporous BiVO(4) for selective oxidation of glycerol to 1,3-dihydroxyacetone – one of the most valuable derivatives of glycerol. Under AM 1.5G front illumination (100 mW cm(−2)) in an acidic medium (pH = 2) without adscititious oxidant, the nanoporous BiVO(4) photoanode achieves a glycerol oxidation photocurrent density of 3.7 mA cm(−2) at a potential of 1.2 V versus RHE with 51% 1,3-dihydroxyacetone selectivity, equivalent to a production rate of 200 mmol of 1,3-dihydroxyacetone per m(2) of illumination area in one hour.
