Direct valorization of cellulose and glucose to glycolic acid through green catalytic process

The current work reports the catalytic conversion of α-cellulose to glycolic acid using molecular oxygen as an oxidant. A series of copper and cobalt molybdophosphoric acid catalysts (Cu-H3PMo12O40 and Co-H3PMo12O40) were synthesized via impregnation and ion-exchange techniques. Then the synthesized...
