The emerging metal–nitrogen–carbon (M–N–C) dual–atom catalysts (DACs) have been expected to generate multicarbon products in the CO2 reduction reaction (CO2RR) due presence of multimetal sites DACs. Unfortunately, numerous recent experiments suggested that almost no DAC could effectively produce a high quantity products. To uncover reason for this phenomenon, we probed surface states typical homonuclear and heteronuclear DACs explored mechanisms CO2RR by spin-polarized density functional theory calculations with van der Waals interactions. Contrary conventional hypothesis C–C coupling can occur through metal-top sites, Pourbaix analyses indicate CO preferentially occupies bridge between two metals, which would hinder subsequent coupling. Moreover, according energy variation, occurring on is not feasible both thermodynamics kinetics. Based derived microkinetic models CO2RR, formation more favorable than other products, consistent current experimental results. Furthermore, found double-side occupancy also if molecules penetrate carbon layer large defect, lead HCOOH CO2RR.
