Electrocatalytic CO2 reduction reaction (CO2RR) to valuable multicarbon (C2+) fuels and chemicals presents a promising strategy mitigate atmospheric accumulation promote the closure of carbon cycle. However, significant challenges persist in achieving both high product selectivity sustained stability CO2RR. In this study, catalytic performance (Fe,Co,Ni,Cu)3O4 medium entropy oxide (MEO) nanoparticles anchored on reduced graphene (rGO) was evaluated for The MEO-rGO catalyst exhibited remarkable activity, cathodic current density -0.5 A cm-2 at -1.7 V, significantly outperforming bare nickel foam (-0.15 cm-2). Additionally, demonstrated total Faradaic efficiency (FE) 60.3% C2+ products, comprising 30.6% C5H12O 29.7% C5H10O. This exceptional toward long-chain hydrocarbons is attributed enhanced C-C coupling surface, facilitated by energy barriers. Density functional theory (DFT) calculations further revealed that adsorption MEO surface are energetically favorable processes.
