DESCRIPTION:Prof. Meng Lin\nAbstract:\nElectrochemical and thermochemical 
 processes offer promising pathways for carbon capture and utilization in p
 ursuit of net-zero emissions. Hybrid strategies are developed to address t
 he challenges of dilute CO2 sources\, including ambient air and seawater\,
  and to enable subsequent catalytic conversion into fuels and chemicals. A
  bipolar membrane electrodialysis (BPMED) platform is employed to selectiv
 ely extract CO2 from seawater through acidity-alkalinity gradients\, achie
 ving high-purity CO2 release and enabling direct electroreduction to carbo
 n monoxide and formate with high Faradaic efficiency [1]. In parallel\, a 
 hybrid electro-thermochemical reactor is designed for direct air capture a
 nd utilization\, in which localized resistive heating of structured cataly
 sts provides high-temperature activation for CO2 hydrogenation\, while ele
 ctrical bias enhances interfacial charge transfer. This coupling of therma
 l and electrical inputs reduces energy intensity and enables efficient met
 hane production under ambient feed conditions [2]. Furthermore\, integrate
 d thermal management and salt precipitation control strategies in CO2 elec
 trolysis are shown to sustain system stability over extended operation [3]
 . Collectively\, these advances demonstrate that combining electrochemical
  and thermochemical approaches can overcome key bottlenecks in dilute CO2 
 capture and utilization\, offering a scalable and energy-efficient route t
 oward sustainable negative-emission technologies.\nRelated Publication by

 essor in the Department of Mechanical and Energy Engineering at the Southe
 rn University of Science and Technology (SUSTech)\, Shenzhen\, where he he
 ads the Solar Energy Conversion and Utilization Laboratory (SECUL). He ear
 ned his PhD (2018) in Mechanical Engineering from EPFL\, Switzerland. From
  2018 to 2019\, he was a postdoctoral researcher at the California Institu
 te of Technology (Caltech)\, affiliated with the Joint Center for Artifici
 al Photosynthesis (JCAP). Since joining SUSTech in 2019\, his research has
  focused on the engineering of solar-driven materials\, devices\, and reac
 tors\, spanning high-temperature thermochemical conversion and solid-oxide
  electrolysis to low-temperature CO2 capture and conversion\, and aiming t
 o enable efficient\, durable\, and scalable pathways to carbon-neutral fue
 ls and chemicals.\n\n
