Electrochem. reduction of CO2 comprising the CO2 reduction reaction (CO2RR) and O evolution reaction (OER) is one of the most promising technologies for electrification of the chem. process industry. Here, the performance of a electrocatalyst with a three-dimensional structure of InZnCu on Cu foam (CF) is presented. This electrocatalyst was fabricated by electrodeposition of In and Zn over Cu and exhibited a superior reduction of CO2 to CO at a faradaic efficiency of 93.7% at -0.7 V and an excellently long duration of 100 h. Due to the synergy of the thin In layer, the Zn nanosheets provided a high surface-active area and strong mech. robustness during the reaction. Addnl., a two-electrode system was constructed based on the CF-modified surface, which provided valuable guidelines on the overall CO2RR-OER system for further evolution. Also, due to the facile synthesis, the bimetal-layer double hydroxide (LDH) exhibited high conductivity and high OER performance. Hence, the two-electrode system assembled excellent electrocatalysts for the CO2RR-OER (InZnCu/CF||Cu(OH)2 NWs@NiCo-LDH/CF) with high conversions of CO2 to CO of 67% and 88% at 2 and 50 mA cm-2, resp. Notably, the CO2RR-OER system exhibited excellent stability in a 40 h CO2 conversion with a constant c.d. of 2 mA cm-2 at an ultralow voltage of 1.59 V. Also, the calculation of the energy input converting CO per ton of CO2 resulted in a low energy input range for further development in scalability. This overall CO2RR-OER proposes development in electrochem. CO2 reduction for industrial applications. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Formula: CuH2O2).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. Copper catalyst has received great attention owing to the low toxicity and low cost. Copper nanoparticles can catalyze the Ullmann coupling reaction in a wide range of applications.Formula: CuH2O2
