Core@shell MOFs derived Co2P/CoP@NPGC as a highly-active bifunctional electrocatalyst for ORR/OER

A review on development of metal–organic framework-derived bifunctional electrocatalysts for oxygen electrodes in metal–air batteries

“…Additionally, the active sites of the carbon foam (CF) are greatly increased by hollow structural architecture. 87 With only low overpotentials of 133 and 289 mV respectively, CoP/Co 2 P/NCNT@CF displayed outstanding catalytic activity for the oxygen evolution reaction and hydrogen evolution reaction in alkaline media. The developed catalysts also have exceptional long-term stability; they continue to have significant catalytic activity even after 20 hours of continuous operation.…”

Effect of Cooperative Redox Property and Oxygen Vacancies on Bifunctional OER and HER Activities of Solvothermally Synthesized CeO2/CuO Composites

“…The literature reports that the unique core−shell structures have a high impact on various electrochemical reactions. 37,38 The internal cavity of the core−shell structure can promote the mass/ion transportation and exposure of the catalytic active sites during the electrochemical reaction, which could improve their electrocatalytic activity. 38 Therefore, enhanced electrochemical performance is expected from this core−shell composite.…”

“…37,38 The internal cavity of the core−shell structure can promote the mass/ion transportation and exposure of the catalytic active sites during the electrochemical reaction, which could improve their electrocatalytic activity. 38 Therefore, enhanced electrochemical performance is expected from this core−shell composite. The corresponding HRTEM image of the 1:1 CeO 2 /CuO composite in Figure 3b clearly shows two distinct sets of lattice fringes with interplanar spacings of 0.24 and 0.32 nm corresponding to the (002) plane of CuO and the (111) plane of CeO 2 , respectively.…”

Direct growth and post-treatment of zeolitic imidazolate framework-67 on carbon paper: an effective and stable electrode system for electrocatalytic reactions

“…22–24 MOF-derived materials with high conductivity and numerous active sites are being extensively employed as catalysts in electrochemical applications, such as supercapacitors, metal–air batteries, and water-splitting processes. 25–29 Transition metal chalcogenides (TMCs), particularly cobalt- and nickel-based catalysts, have been introduced as excellent electrocatalysts for the oxygen evolution reaction (OER). 30–32 TMCs derived from MOFs exhibit outstanding catalytic activity owing to the high exposure of active sites, efficient mass transfer, and high structural integrity.…”
