Al-Doped Octahedral Cu₂O Nanocrystal for Electrocatalytic CO₂ Reduction to Produce Ethylene.

ABSTRACT: Ethylene is an ideal CO₂ product in an electrocatalytic CO₂ reduction reaction (CO₂RR) with high economic value. This paper synthesised Al-doped octahedral Cu₂O (Al-Cu₂O) nanocrystal by a simple wet chemical method. The selectivity of CO₂RR products was improved by doping Al onto the surface of octahedral Cu₂O. The Al-Cu₂O was used as an efficient electrocatalyst for CO₂RR with selective ethylene production. The Al-Cu₂O exhibited a high % Faradic efficiency (FE_C2H4) of 44.9% at -1.23 V (vs. RHE) in CO₂ saturated 0.1 M KHCO₃ electrolyte. Charge transfer from the Al atom to the Cu atom occurs after Al doping in Cu₂O, optimizing the electron
