The production of DMF results from the hydrogenation and hydrogenolysis of 5-Hydroxymethylfurfural (HMF). Hydrogenation processes often require purging the system with high pressure hydrogen to increase the solubility of hydrogen in the solvent, all the while using high temperatures for the hydrogenation reactions to occur. Herein, we proposed a novel method in which DMF could be synthesized in high yields under atmospheric pressure and room temperature. A bifunctional Pd/CoNC material of ZIF-67 descent was synthesized in which Palladium provides a hydrogenation surface and Cobalt catalyzes the production of hydrogen from an aqueous source, Sodium Borohydride (NaBH4). The synergetic effects of Cobalt and Palladium on the same support helped achieve 83.07% DMF yields.1. INTRODUCTION 1 1.1. ENERGY CRISIS 1 1.2. BIOMASS DEVELOPMENT 4 1.3. BIOMASS CONVERSION 6 2.
