## Abstract

Amino acid-loaded Cu2O hybrid particles were synthesized via microwave-assisted hydrothermal reaction for efficient CO2 reduction. The amino acid-loaded Cu2O particles exhibited different selectivities in the CO2 electrolysis products depending on type of loaded amino acid. Notably, as compared to amino acid-unloaded Cu2O particles, the l-histidine-loaded Cu2O hybrid particles exhibited an improvement of faradaic efficiency to 18.5% toward ethylene production.
