报告摘要：

Metal-organic frameworks (MOFs), are crystalline porous materials constructed by connecting metal ions/clusters with organic linkers (such as multi-dentate carboxylates). The highly dispersed and uniformly distributed metal sites can be tailored in MOFs, endowing them the great yet versatile capacity for various applications such as catalysis. However, to date, MOFs have found limited practical applications in catalysis primarily due to their poor thermal and hydrolytic stability. This severely restricts their applications in conventional catalysis involving thermal treatment and/or use of water.Now, Fan and other colleagues at The University of Manchester have proposed and developed innovative low temperature plasma processes to activate the intrinsic catalytic properties and to sustain the stability of MOFs for the challenging catalysis of the water-gas shift reaction for hydrogen production which normally only occurs at high temperature. Importantly, the stability of MOFs is sustained under plasma activation and in the presence of water. The method has been proven to be generic, and therefore has the potential to be a platform technology enabling the utilisation of MOFs for a wider range of catalysis, such as catalytic reduction of nitrogen oxides (NOx) for emission control.

Structured foam catalysts are technologies which address challenges in catalytic processes due to the mass and heat transfer limitations. In this presentation, the preparation of structured silicon carbide (SiC) foam catalysts, especially the zeolites/SiC foam catalysts, via a dispersion-based method will be presented, showing the controlled synthesis of thin and uniform catalytic layers on SiC foam supports. Finding from the comparative studies of various cases including methanol-to-propylene (MTP), catalytic cracking of n-hexaneand bio-oils upgrading (methanol and anisole as model compounds) over structured ZSM-5/SiC foam catalysts in reference to the conventional ZSM-5 pellets catalysts will be presented and discussed in details to understand the process intensification effects by the structured ZSM-5/SiC foam catalysts. Additionally, a detailed analysis of the deactivation mechanisms of the structured ZSM-5/SiC foam and the conventional ZSM-5 pellet catalysts will be discussed, revealing the effect of foam-induced process intensification on the deactivation of zeolite catalysts.
