Microwave-assisted hydrothermal synthesis of amino acid-loaded Cu2O hybrid particles for CO2 reduction electrocatalysis†

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.
