Highly selective electrocatalytic CO2 reduction to ethanol by metallic clusters dynamically formed from atomically dispersed copper

CO2valorisation towards alcohols by Cu-based electrocatalysts: challenges and perspectives

“…They demonstrated through DFT calculations that the improved performance of this material is due to the suppression of the deoxygenation process, because of the strong electron-donating ability of the confining N-C layer. Xu H. et al 93 Some recent studies have shown Cu-based materials with other non-metal dopants different than nitrogen, such as sulphur (e.g. Cu 2 S-Cu-V).…”

“…Faradaic efficiencies and partial current densities of the best liquid-phase EC CO 2 R electrocatalysts towards methanol, ethanol and n-propanol production. Authors with data taken from 62,73,74,83,84,[90][91][92][93][94][95][96][97][98][100][101][102]124 .…”

“…In this regard, as previously discussed, systematic in situ and in operando characterizations have been developed and used in some research works to identify and monitor the copper actives sites under reaction conditions. 62,71,78,90,[93][94][95]97,98,136,168 However, the stability of Cu ⸹+ is of special concern under electrochemical reduction conditions; e.g. time-resolved in situ soft X-ray absorption spectroscopy studies demonstrated that the initial transition step from Cu 2+ to Cu + is very quick, while the further electrochemical reduction of Cu + to Cu 0 is much slower.…”

Efficient electroreduction of CO2to C2+products on CeO2modified CuO

“…[1][2][3][4][5][6] Continuous progress has been made in the eld of the electrochemical CO 2 reduction reaction (CO 2 RR), especially for monocarbon products like carbon monoxide (CO) and formate. [7][8][9][10][11][12][13][14][15][16] However, the manufacture of valuable C 2+ products in CO 2 RR, such as ethylene (C 2 H 4 ), ethanol (C 2 H 5 OH) and n-propanol (n-C 3 H 7 OH), still has to balance selectivity and activity, [17][18][19][20][21][22][23][24][25] which obstructs further industrial applications. To achieve a commercial current density (>100 mA cm À2 ) as well as high selectivity for C 2+ products in CO 2 RR, [26][27][28][29][30][31][32] highly efficient and robust electrocatalysts are required.…”

From double‐atom catalysts to single‐cluster catalysts: A new frontier in heterogeneous catalysis

“…Unlike SACs, the biggest advantage of supported metal complex‐site catalysts is the interaction between adjacent metal atoms. [ 108 ] Interaction between metal atoms in DACs/SCCs helps to adjust the electronic structure of catalytic active sites, effectively improving the catalytic performance. [ 64,109,110 ] This section reviews the synergy between metal atoms from two aspects: DACs and SCCs.…”
