Glucose oxidation assisted ammonia production via electrochemical dinitrogen reduction over CoWO₄

Abstract

Electrochemical N2 reduction reaction (NRR) under ambient temperature and pressure is an environmental-friendly method for N2 to NH3 conversion. Nevertheless, the overall energy input can be reduced by replacing sluggish...

Covalent Organic Framework Bifunctional Catalyst for Glucose Oxidation Reaction Coupled Nitrate to Ammonia Electrolysis

“…To take the NO 3 RR a step further, it is essential to consider the accompanying oxygen evolution reaction (OER) at the anode in the full cell (NO 3 RR-OER) electrolysis. The sluggish kinetics of OER due to high energy demand for O–O bond formation (4e – transfer) become the bottleneck for the effective synthesis of NH 3 . − Alternatively, substituting the OER at the anode by other thermodynamically more feasible oxidation reactions, viz., the glucose oxidation reaction (GOR), thus decreases an energy input for ammonia synthesis along with the value-added products at the anode (NO 3 RR-GOR). This strategy provides a proficient assimilation of two industrially important areas, i.e., anodic oxidation of glucose to glucaric/gluconic acid − along with enhanced ammonia production at the cathode while lowering the overall potential, subsequently increasing its economic value.…”
