Atomically Dispersed Fe-Co Bimetallic Catalysts for the Promoted Electroreduction of Carbon Dioxide

“…The state-of-art ECO 2 RR catalyst design focuses on metal-based catalysts. For example, Cu-based catalysts are exclusively effective for the production of alcohols/hydrocarbons; Ag, Au, and Zn, or most recently the atomically dispersed M–N-C catalysts are efficient for CO production [ 6 , 7 ]. Single-atom catalysts (SACs) are known for their efficient active sites, maximized utilization of metal atoms, and low cost.…”

Mechanistic understanding and design of non-noble metal-based single-atom catalysts supported on two-dimensional materials for CO2 electroreduction

“…The accuracy and predictive power depends strongly on the input features, ML algorithms, and the quality as well as size of training and test database. 29 Therefore, more studies and efforts are still required to use universal descriptors as input features, use a general ML algorithm, and increase the input database. 164 Moreover, the descriptors obtained from ML can be helpful for constructing volcano plots to understand the origin of SAC activity.…”

Boosting CO2 electroreduction to C2+ products on fluorine-doped copper

“…1–3 Electrochemical conversion of CO 2 meets the requirements of green chemistry and carbon neutrality, because it would take advantage of clean and renewable electricity. 4–7 Much effort has been made to develop the electroreduction of CO 2 and significant advances have been achieved towards the generation of valuable products. Up to now, monocarbon products (carbon monoxide, formate, methane and methanol) could be efficiently obtained from the electroreduction of CO 2 both in aqueous electrolyte or ionic liquid.…”
