The results show that CO mainly converts into CO 2 through the reaction CO + OH → HOCO → CO 2 + H. The intermediate HOCO can also react with OH or O 2 to form CO 2. The overall activation energies of CO oxidation in the supercritical medium range from 125.3 ± 4.0–159.4 ± 3.6 kJ/mol, which are roughly consistent with the experimental 1 mole of calcium hydroxide reacts with 1 mole of carbon oxide to produce 1 mole of calcium carbonate and 1 mole of water. Ca ( OH) 2 + CO 2 → CaCO 3 + H 2 O. This is the balanced chemical equation as the reaction is already balanced. Suggest Corrections. 70.

Dalton Trans. 2022. Abstract In recent years, Co-based metal-organic frameworks (Co-MOFs) have received significant research interest because of their large specific surface area, high porosity, tunable structure and topological flexibility. However, their comparatively weak electrical conductivity and inferior stability drastically restrict the application of Co-MOFs in the synthesis of electrocatalysts. In this study, ZIF-67 was grown on nickel foam by a room temperature soaking method, and then Ir-Co(OH)2@ZIF-67/NF was assembled by a hydrothermal method. The prepared Ir-Co(OH)2@ZIF-67/NF nanosheets exhibit remarkable conductivity, larger electrochemical active surface area and wider electron transport channels. Only ultralow overpotentials of 198 mV, 263 mV, and 300 mV were needed for Ir-Co(OH)2@ZIF-67/NF to reach the current densities of 10 mA cm-2, 50 mA cm-2, 100 mA cm-2, meanwhile, no obvious degradation of the current density at 10 mA cm-2 was observed for about 16 h. This work may provide a promising strategy for developing high-performance MOF-derived materials as electrocatalysts for the OER under alkaline conditions.

Polymers (Basel). 2022. Free PMC article Abstract It is critical to develop efficient oxygen evolution reaction (OER) catalysts with high catalytic properties for overall water splitting. Electrocatalysts with enriched vacancies are crucial for enhancing the catalytic activity of OER through defect engineering. We demonstrated the dealloying method in a reducing alkaline solution using the Co5Al95 alloy foil as a precursor to produce a new oxygen-vacancy-rich cobalt hydroxide (OV-Co(OH)2) hierarchical dendrite. The as-synthesised OV-Co(OH)2 showed superior electrocatalytic activities toward OER when compared to pristine cobalt hydroxide (p-Co(OH)2), which had a low onset overpotential of only 242 mV and a small Tafel slope of mV dec-1. Additionally, for the high surface area provided by the hierarchical dendrite, both p-Co(OH)2 and OV-Co(OH)2 showed a superior activity as compared to commercial catalysts. Furthermore, they retained good catalytic properties without remarkably decaying at an overpotential of 350 mV for 12 h. The as-made OV-Co(OH)2 has prospective applications as an anode electrocatalyst in electrochemical water-splitting technologies with the advantages of superior OER performances, large surface area and ease of preparation.
