Abstract

Co-electrolysis of bio-oil (derived from the fast pyrolysis of lignocellulosic biomass) and CO2 to produce sustainable and carbon-neutral chemicals offers a promising approach for simultaneous bio-oil upgrading and CO2 fixation. Despite variations in raw materials, bio-oil shares common functional groups, comprising aromatic-poor fractions (APF, mainly from cellulose and hemicellulose) and aromatic-rich fractions (ARF, mainly from lignin), whose interactions significantly influence the electrochemical upgrading of bio-oil. In this study, building on our previously proposed method of co-electrolysis of bio-oil and CO2, we further investigated the roles of the interactions between APF and ARF on bio-oil upgrading and CO2 fixation. Results showed that the interactions suppressed CO2 fixation, promoted CO2 conversion, improved product selectivity of organic acids, and inhibited polymerization. Notably, the interactions between acetophenone and ARF significantly enhanced the formation of organic acids, with a 136.55 % increase in their content. Furthermore, the interactions facilitated the conversion of larger molecular compounds (350–450 Da) into smaller molecular compounds (<300 Da) during co-electrolysis of bio-oil and CO2. In conclusion, we proposed a mechanism for bio-oil upgrading and CO2 conversion, influenced by interactions between APF and ARF during the co-electrolysis, providing valuable insights into the synergistic processing of bio-oil from various sources with CO2.
