We are excited to invite you to our next online workshop, organized in collaboration with the University of Manchester. Advanced sorption techniques can be essential characterization tools in the research or catalysts, porous solids, and medical care materials. In this session, we will give you a deep understanding of advanced gravimetric sorption techniques, such as Dynamic Vapor Sorption (DVS) and Inverse Gas Chromatography (iGC), and how they can be employed to gain unparalleled detail and accuracy in materials research.

Along with special guest speaker Dr. Xiaolei Fan (University of Manchester) exploring some of his recent research, the workshop will feature two leading Sorption Science experts from Surface Measurement Systems, Dr. Vladimir Martis and Meishan Guo, who will be sharing their expertise.

Porous materials play an important role in capturing Volatile Organic Compounds (VOCs), SO2, or CO2 from the air.  Understanding the sorption properties of the porous solids is crucial in developing mechanical systems and their operating conditions. The measurement of single component water or organic vapor sorption isotherms and CO2 or SO2 adsorption/desorption isotherms up to 1bar is a first step in the selection of the materials for removal of hazardous molecules. The next step is to study the co-sorption behaviour of these materials when water is present. Dynamic Vapor Sorption Vacuum (DVS Vacuum) is a powerful gravimetric vapor/gas sorption analyzer for measuring single component and multicomponent sorption isotherms in a broad temperature range.  In this talk, we will present single component and multi-component sorption isotherm and kinetics data of porous solids for various ranges of probe molecules in dry and humid conditions.

The surface energy of the starting, intermediate or final products is an important factor in understanding the processing operation and/or the final product performance. This study will consider the surface energy and surface energy heterogeneity of crystalline solids, methods for the measurement of surface energy, effects of milling on powder surface energy, adhesion and cohesion on powder mixtures, crystal habits and surface energy as well as surface energy and powder granulation processes to predict agglomeration and powder flow behaviour, using surface energy heterogeneity and work of adhesion to cohesion ratio as the parameters.

Porous materials are workhorses in many applications especially gas separation and adsorption and catalysis. Both old-era zeolites and new-era metal-organic frameworks (MOFs) have been of interests to the scientific community due to their great tunability in porous structures and chemical properties for various applications. In this talk, a brief introduction will be given to showcase the current research in Fan’s group regarding the development and application of various porous materials including microporous zeolites and MOFs, mesoporous zeolites and cellular microporous foams. Specifically, Cu3(BTC)2 framework (copper benzene-1,3,5-tricarboxylate or HKUST-1), a well-studied MOF for gas separation and storage, will be discussed regarding its hydrothermal stability for CO2 adsorption. Relevant work using dynamic water vapour adsorption experiments will be discussed for the purpose of investigating the hydration process of HKUST-1 framework under various humid conditions and assess its moisture stability.

Xiaolei Fan (CChem, FRSC) received his PhD in Chemical Engineering from the University of Bath in 2010. From 2010 to 2013, he took the postdoctoral positions at the University of Warwick and University of Cambridge, focusing on the research in heterogeneous catalysis and reaction engineering. Currently, he is a Reader in the Department of Chemical Engineering at The University of Manchester. His research broadly encompasses the heterogeneous catalysis, porous materials, catalytic reaction engineering, process intensification and structured catalysts/reactors. Currently, he focuses specifically on development of novel systems based on functional porous materials for carbon capture and catalytic carbon conversions. His research was recognised internationally with several awards such as the Lee Hsun Young Scientist Lecture award on Materials Sciences by the Chinese Academy of Sciences (2018), RSC Emerging Investigators (2019) and ACS I&EC Research 2020 Influential Researchers (2020).
