Most current climate models suggest that limiting warming to <2°C will require large scale deployment of carbon dioxide removal (CDR) technologies. CDR may be natural or technological, with one of the most scalable technological approaches being the direct capture of CO2 from the air, or “direct air capture” (DAC) coupled with geologic storage. Because of the ultra-dilute nature of air, the separation of CO2 from this mixture presents a significant engineering challenge. Today, DAC technologies are very expensive ($500-1000/tCO2).
In this lecture, I will describe the unique challenges associated with designing molecules, materials, devices and ultimately processes for DAC. Specifically, I will describe the design and synthesis, characterization and application of porous oxide-supported amine materials that we have developed as cornerstones of new technologies for the removal of CO2 from air. These materials are incorporated into customized air/solid contactors designed specifically as key components of DAC technologies. DAC offers an interesting case study for the parallel and integrated design of materials, unit operations, and processes in chemistry and chemical engineering.

演讲主题：Direct Air Capture of CO2: Chemistry & Engineering Combine for Climate Stabilization

Professor Jones is the John F. Brock III School Chair and Professor of Chemical & Biomolecular Engineering at Georgia Tech. He joined Georgia Tech as an Assistant Professor in 2000 and previously served as Associate Vice President for Research from 2013-2019. Dr. Jones leads a research group that works on materials, catalysis and adsorption. He is known for his extensive work on materials that extract CO2 from ultra-dilute mixtures such as ambient air, which are key components of direct air capture (DAC) technologies. For this reason, he served on two US National Academies Consensus Studies on climate change mitigation. Jones also has produced an extensive body of work in catalysis. Dr. Jones was the founding Editor-in-Chief of the journal, ACS Catalysis, and was Vice-President of the North American Catalysis Society from 2017-2025. Today he leads the open access, multidisciplinary journal, JACS Au, as founding Editor-in-Chief, and serves as the President of the International Adsorption Society.
Jones’ work in both catalysis and CO2 separation has been recognized with awards from numerous organizations including the ACS, AIChE and North American Catalysis Society. These include the top US early career catalysis award – the Paul H. Emmett Award in Fundamental Catalysis (2013) and the top US mid-career chemical engineering award the Andreas Acrivos Award for Professional Progress in Chemical Engineering (2016). Jones was elected to the US National Academy of Engineering in 2022 and the US National Academy of Inventors in 2023.
