DESCRIPTION:Abstract:\nCarbon dioxide (CO2) is a major greenhouse gas whic
 h is driving the climate change. Electrochemical processes offer good reac
 tion selectivity and reduced cost because of the possibility of direct con
 trol of electrode surface free energy through the electrode potential. Con
 verting CO2 to valuable fuels and chemicals using electrochemical catalyti
 c reduction (eCO2R) with renewable electricity has attracted growing inter
 est aiming to reduce CO2 emission and energy security. With specific catal
 ysts GDE eCO2RR demonstrated good selectivity with FE > 90% and overall on
 e pass conversion >18% for C1 products were achieved. Multi-carbon product
 s\, C2 and C3\, were synthesised with bi-metallic Cu-Ag prepared by electr
 ochemical spontaneous deposition of Ag on Cu2O nanoparticles. From the den
 sity functional theory (DFT) analysis\, Ag promotes Cu atoms migration tow
 ards the surface of the electrode\, which seems to adsorb generated CO for
  the further reduction process to produce C2+ carbonaceous products. CuAg 
 has shown some promising CO2 reduction with 60% FE corresponding to C2+ pr
 oducts.\nMicrobial electrosynthesis with microorganisms enriched from acti
 vated sludge\, converting CO2 to acetate\, C4 and C6 compounds\, through W
 ood-Ljungdahl pathways. Integrated processes combining biological and elec
 trochemical processes can provide a crucial route to achieve a sustainable
 \, non-fossil fuel based chemical production with renewable energy. The sy
 stem may be enhanced with photo-electrochemical process to achieve a susta
 inable\, non-fossil fuel based chemical production for accomplishing Susta
 inable and Circular chemical Economy.\n\nBio:\nProfessor Eileen Yu holds a
  Chair of Chemical Engineering in the School of Chemistry and Chemical Eng
 ineering\, University of Southampton. After obtaining her PhD from Newcast
 le University pioneering on the development of direct methanol alkaline fu
 el cells\, she worked as a research fellow at Max Planck Institute for Dyn
 amics of Complex Technical Systems\, Germany before she returned to Newcas
 tle University to take a prestigious EPSRC Research Fellowship (Life Scien
 ce Interface). This fellowship enabled her to extend her research into the
  biosciences\, from which she has developed an interdisciplinary research 
 profile.\nShe has a wide range of experience in various fields in electroc
 hemical and bioelectrochemical systems for energy\, environmental and biom
 edical applications. She has attracted funding from various funding organi
 sations. Her current research includes understanding fundamentals and engi
 neering applications of electrocatalysis and microbial electrosynthesis fo
 r CO2 utilisation\, nitrogen fixation\, resource recovery from wastes\, bi
 oremediation and environment monitoring with bioelectrochemical systems.\n
 She is the Editor in Chief of Fuel Cells (Wiley)\, and Associate editor fo
 r Frontiers in Energy Research\, Biosensors etc..\n
