Improving the lifetime of hybrid CoPc@MWCNT catalysts for selective electrochemical CO2-to-CO conversion

Metal-Coordinated Phthalocyanines as Platform Molecules for Understanding Isolated Metal Sites in the Electrochemical Reduction of CO2

“…The syngas (CO/H 2 ) ratio also indicates that Co-Pc is efficient at selectively converting CO 2 into CO, as shown in Figures C and S8. The FE­(CO) and J (CO) values of the catalysts in this study are tabulated in Table S4 in comparison with those of similar TM-Pc-based catalysts. − It is important to point out that the primary focus of the current study is to compare the CO 2 RR performance of different TM-Pc molecules under identical electrochemical conditions to determine the intrinsic role of isolated TM. Considering that the TM-Pc structure has been often employed as a structural model of TM-SACs due to the potential presence of TM-N 4 complex in the TM-SACs, − ,− ,− the selective CO production of Co-Pc should be counterintuitive against the previous works. − This is because Co-based SACs have been reported to be exclusively active for HER rather than CO 2 RR.…”

Acidic CO2 electroreduction for high CO2 utilization: catalysts, electrodes, and electrolyzers

“…(a) Selectivity versus stability of CO 2 RR catalysts in acidic, neutral, or alkaline electrolytes. 17,18,21,32,42,44,47,48,53,119,[125][126][127][128][129][130][131][132][133][134][135][136] behavior is advantageous for increasing catalyst stability because the reconstructed catalyst structure will actively participate in the reaction. Nonetheless, there is less understanding about the reconstruction of CO 2 RR catalysts in an acidic electrolyte, and predicting alterations in the catalyst morphology during the catalytic reaction remains challenging.…”

Recent Advances in the Use of CoPc-MWCNTs Nanocomposites as Electrochemical Sensing Materials

“…Aside from these, CoPcMWCNTs nanocomposite have been utilized in various other processes such as oxidation of styrene to benzaldehyde [ 7 , 75 , 76 ], catalytic oxidation of benzyl alcohol to benzaldehyde [ 6 , 25 ], electrochemical reduction of oxygen [ 77 , 78 , 79 , 80 , 81 ], electrochemical conversion of CO 2 to CO [ 82 ], removal of mercaptan from natural gas [ 83 ], photocatalytic oxidation of butan-2-ol [ 84 ], a catalyst for microbial fuel cell [ 85 ], catalyst in glucose/O 2 fuel cells [ 86 ], and electrochemical reduction of carbon dioxide and carbon monoxide to methanol [ 87 ]. The conversion rate and selectivity recorded in these processes were satisfactory.…”
