报告人简介：
Tianyi Ma is a RMIT University Distinguished Professor, an Australian Research Council Future Fellow, Fellow of Royal Society of Chemistry, and Clarivate’s Global Highly Cited Researcher. He is Director of ARC Industrial Transformation Hub for Intelligent Energy Efficiency in Future Protected Cropping (E2Crop), and Research Director of Centre for Atomaterials and Nanomanufacturing (CAN). His international standing is evidenced by >600 publications in top-tier journals with an H-index of 115 and >55,000 citations. His ground-breaking research has been acknowledged by internationally recognised experts and authorities via 2024 Prime Minister's Prize for Science - the Malcolm McIntosh Prize for Physical Scientist of the Year, AAS Le Févre Medal, Young Tall Poppy Science Award, ARC Discovery Early Career Researcher Award, and Horizon Prize of Royal Society of Chemistry. His scientific impact and leadership are also evidenced by supervision of over 40 Ph.D. students, secured more than AU$45m in government and industry funding, and heavy engagement in international academic roles, such as Associate Editor, Editorial Board Member and Guest Editor for over 15 international journals. He focuses on developing fundamental scientific breakthroughs and also up-scaling prototypes with far-reaching industry influence and real-life applications. Demonstrations and pilot plants have been established locally in Australia to drive his technologies to practical deployment and commercialisation, for example, the square meter sized solar-to-hydrogen generator, kilowatt level CO2 electrolyser, kilogram-sale formic acid production micro-pilot plant, and high-energy density battery packs, which may change the way how society generates and consumes energy and chemicals.
讲座摘要：
Carbon capture and utilization (CCU) technologies are critical to achieving net-zero emissions, yet conventional CO2 electroreduction requires energy-intensive desorption and purified CO2 feedstocks, limiting industrial adoption. We report a disruptive liquid-phase amine-captured CO2 electrolysis platform that directly converts CO2 from post-combustion flue gases into value-added C1 and C2 products without intermediate release, functioning as a plug-and-play module with existing amine scrubbing facilities. By co-optimizing catalyst architecture, interfacial engineering, and electrolyte composition, the system enables tunable selectivity toward CO, formate, and ethylene while maintaining tolerance to real-world flue gas impurities. Mechanistic insights from in situ spectroscopy and density functional theory reveal the key roles of catalyst–amine–CO2 interactions in driving high-efficiency conversion. Compared to conventional CCU routes, our approach achieves ~60% lower energy consumption and up to 70% lower capital costs, while eliminating the need for costly CO2 purification. Recent progress includes the development of metal–nitrogen–carbon frameworks and bimetallic interfaces optimized for continuous-flow operation, as well as pilot-scale demonstrations integrated with renewable electricity sources. This one-step capture–conversion process addresses critical bottlenecks in the CCU value chain, offering a scalable and economically compelling pathway for industrial carbon management.
