Conversely, increasing the glycerol concentration reduced both the yield and selectivity of 3C products. At a glycerol concentration of 1 M, GLYD was the main product, with a selectivity of 51%.

Selective oxidation of glycerol is challenging due to its structure. Glycerol has three -OH groups: two on primary carbon atoms and one on a secondary carbon atom.
