Jin’s group has recently published a review paper “Artificial channels for confined mass transport at the sub-nanometre scale” in Nature Reviews Materials (https://www.nature.com/articles/s41578-020-00268-7).

Over the past decade, materials with nanochannels that selectively transport gases, liquids and ions at a sub-nanometre (sub-nm) scale, have received considerable attention from both academia and industry. Such materials exhibit unique properties that find numerous applications in key areas including catalysis, energy storage and conversion, molecular separation, and bio/chemical sensors. However, their practical applications have continuously faced challenges with respect to efficiency, stability and scalability.

In this review, we present a comprehensive review of the state-of-the-art research on artificial channels in the platforms of well-defined nanopores, 1D nanotubes, and 2D nanochannels, and discuss their design principles, microstructure, and fabrication. We focus on fundamental mechanisms of sub-nm confined mass-transport and their relationships with the structure–property–performance. We then present the practicalities of these channels and discuss their potential impact on the development of next-generation sustainable technologies for use in applications related to energy, the environment and healthcare.

南京工业大学金万勤教授团队受邀在国际顶尖学术期刊Nature Reviews Materials上发表题为“Artificial channels for confined mass transport at the sub-nanometre scale”的综述文章(https://www.nature.com/articles/s41578-020-00268-7)。

具有亚纳米限域传质通道的膜材料用于气体、液体和离子的选择性分离一直以来都是国际学术界和工业界的研究热点。这些膜材料在催化,能源存储与转化,分子分离和生物化学传感等诸多领域都具有极大的应用前景。然而膜材料的实际应用在传质效率,稳定性和规模化制备等方面仍存在诸多挑战。金万勤教授团队在国际上首次全面综述了亚纳米限域传质通道,包括纳米孔、一维纳米管及二维纳米通道在设计原理、微结构调控和规模化制备等方面的最新研究成果,并深入讨论了亚纳米限域传质机理和纳米通道的构效关系。该综述文章为亚纳米通道膜材料的发展提供了理论指导,并对下一代可持续发展技术用于能源、环保、智能电子和医疗健康等领域具有促进意义。
