Incorporation of Manganese Carbonyl Sulfide ((Mn2S2 (CO)7) and Mixed Metal Oxides-Decorated Reduced Graphene Oxide (MnFeCoO4/rGO) as a Selective Anode Toward Efficient OER from Seawater Splitting Under Neutral PH Conditions
Abstract
Herein, we propose a novel material combination, which exhibits higher OER activity and selectively over chlorine evolution reaction (CER) during simulated saline water electrolysis under neutral pH conditions. The proposed hybrid nanocomposite system, based on electroactive mixed metal oxides-decorated reduced graphene oxide (MnFeCoO4/rGO) which is incorporated with manganese carbonyl sulfide (Mn2S2(CO)7), are fabricated by a single-step hydrothermal technique. Benefiting from their heterogeneous interfaces, lower charge transfer resistance, and higher electrochemical (EC) and BET surface area, the hybrid graphene MnFeCoO4/Mn2S2(CO)7 nanocomposite (HGNC) yields the best performance among various options towards OER from pH-neutral seawater (1 M PB + 0.6 M NaCl; pH 7.0) electrolysis, with small Tafel slope of 74.1 mVdec-1 and correspondingly low overpotential of ∼310 mV to achieve a current density of 10 mAcm-2. The high activity at the aforementioned current density allows for overpotential operation below the minimum thermodynamic requirement needed for activating CER, thus ruling out progression of CER. Further, benefiting from the strong coupling effect between the MnFeCoO4/Mn2S2(CO)7 species and the graphene support, appreciable stability was achieved for 15 hours to deliver steady-state current stability without obvious decay, which demonstrating that HGNC is a promising candidate as an OER electrocatalyst for neutral seawater electrolysis.
