description: Bio-oil upgrading by electrocatalysis requires significant technical innovations so as to compete with thermocatalytic processes that have significantly higher catalytic activity. In the present study, the primary advantage of in-situ hydrogen supply from water electrolysis is combined with the development of non-noble metal catalysts for the bio-oil electrocatalytic hydrodeoxygenation (ECH-DO) reaction. Furthermore, the well-established technology of paired electrosynthesis is applied to bio-oil ECH-DO with anodic coupling electrosynthesis (ACE), utilizing the glycerol electrooxidation reaction, creating product intensification and increasing process energy efficiency. Firstly, the study assessed candidate anodic reactions using multi-objective optimization (MOO) based on six key elements: safety, environment, energy, economics, separation, and technology readiness level. Secondly, the selected ACE and bio-oil ECH-DO were optimized individually in different electrolyte pairs using noble metal catalysts in a divided stirred slurry electrocatalytic reactor (SSER). Thirdly, the paired electrosynthesis of guaiacol (as bio-oil model compound) electrocatalytic hydrodeoxygenation (GECH-DO) and the ACE was assessed to find the best operating conditions in terms of agitation speed, initial concentration, current density, temperature, and metal loading. Lastly, tailored binary (PtNi/C and PtCo/C) and ternary (PtNiCo/C) electrocatalysts were introduced and compared with the existing reference electrocatalyst (Pt/C). Glycerol electrooxidation (GEOR) to glyceraldehyde was the best candidate for the anodic electrosynthesis based on the MOO analysis. Results showed that 25% isopropanol (IPA) in the catholyte triggered the dehydration reaction of guaiacol towards cyclohexane. Furthermore, the Pt/C catalyst had the highest catalytic activity for GECH-DO and GEOR for glyceraldehyde production, compared to Ru/C and Pd/C. The paired electrosynthesis was favored in acid-acid electrolyt…
