Enhanced Hydrazine Oxidation on Histidine-Functionalized Graphene-Based Electrocatalysts

Abstract: One of the most essential processes in industrial and other potential energy applications is the electrochemical hydrazine oxidation reaction (HzOR). With an onset potential of 0.75 V versus reversible hydrogen electrode (RHE), the electrochemical HzOR performance of histidine-functionalized graphene oxide (Hist@rGO) is substantially enhanced with an achieved higher current of 24 mA/cm 2 at 1.95 V versus RHE in 0.5 M KOH. Hist@rGO has the highest electrocatalytic performance for hydrazine oxidation processes a… Show more

“…Hydrazine has emerged as a major component among the various possibilities for fuel cells due to its numerous positive properties. 143–145 It possesses a substantially higher theoretical voltage and power density, making it a tempting option. The hydrazine oxidation reaction (HzOR) has garnered significant attention owing to its low theoretical oxidation potential (−0.33 V vs. RHE), environmentally benign byproduct (N 2 ), and its compatibility with electrolyzers that do not require separators.…”

“…These catalysts are also used for hydrazine oxidation assisted hydrogen generation. The thermodynamic potential for hydrazine oxidation is −0.33 V vs RHE (N 2 H 4 + 4OH – = N 2 + 4H 2 O + 4H + ), which is significantly lower than that for the OER (1.23 V). , With hydrazine being easier to oxidize than water, a hydrazine–water mixture is often used to eliminate the overpotential and kinetic barrier associated with the water oxidation half-cell. Moreover, hydrazine assisted water splitting will afford N 2 as a gaseous byproduct, which is safer than the production of O 2 in the anodic compartment.…”
