讲座摘要/Abstract:

    吴宇恩教授课题组,近些年来一直专注于催化剂的理性设计及精细调控,并将其应用于能源小分子“化学键”的精准活化。发展了自上而下的合成策略实现了高金属载量、配位结构均一的单原子催化剂的可控制备,实现了对活性中心金属-金属键、配位数等原子结构的精准调控,并将其应用于氧分子等能源小分子的精准活化。利用主客体策略实现了具有双原子中心的燃料电池阴极催化剂合成,解决了非Pt催化剂在酸性条件下不稳定的难题;采用表面缺陷工程策略制备了高效廉价的Ru单原子合金电解水催化剂,相比于商业Ru基催化剂成本和稳定性提升了两个数量级。发展了原子蒸发法,解决了大规模制备中均一性的问题面向不同的工业应用场景开发了多达200多种单原子催化剂,建立了单原子催化剂的大数据库和年产超1000吨的生产线开发了系列高效活化氧的杀菌、除藻、抗病毒产品,目前已经应用于细菌和病毒的防护、空气净化、水污染处理等多个领域。开发了一种全新的氧气调控技术——电子氧肺技术,可安全、高效的实现氧气的富集和脱除。未来,我们拟开发面向医疗供氧、粮食储藏、食品保鲜、冶金、化工合成等行业的制氧、除氧、控氧反应器,开发多款针对不用使用场景的以电子氧肺技术为核心的高效氧气调控原型设备。目前,已经实现多项成果转化并产生超千万产值。

    Wu lab have dedicated in systemic design and pinpoint control of advanced catalysts and their application in small molecule activation. They have achieved controllable synthesis of high metal loading single-atom catalysts with uniform coordination geometry via a top-down strategy. Through this, control over active center-metallic bond, coordination number, activation of small molecule such as oxygen, etc., have been made possible. Through a Host-Guest strategy, fuel cell anode with diatomic center has been synthesized to compensate the instability of non-Pt catalysts under acidic conditions. They have also designed Ru single atom catalyst for water electrolysis with excellent efficient and low cost through surface defect engineering, which surpasses commercial Ru catalysts by two magnitude on both stability and cost efficiency. Moreover, Wu lab have improved atomic evaporation to increase the uniformity in mass production processes. They have developed over 200 single-atom catalysts to a variety of industries, with over 1000 tons of production per year. Based on such achievement, a Big Data database of single atom catalysts have been built. A series of antibacterial, algaecidal and antiviral products through activated oxygen have been developed for biomedical protection, air purification and water treatment, etc. They also designed an electronic oxygen generator which represents the function of lung by controlling oxygen enrichment and desorption safely and efficiently. In the future, there will be equipments with oxygenation, deoxygenation and accurate control of oxygen level for medical industry, food storage, metallurgy and chemical industry, etc. Also, a series of equipments with advanced oxygen regulation are in prototyping stage base on the electronic oxygen generator technology. Commercialization of the above technologies have yielded over 10 million RMB.
