Low-temperature plasma activates metal-organic frameworks for catalytic reactions<\/strong><\/p>\n

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.<\/p>\n

Now, chemical engineers at The University of Manchester together with colleagues in Belfast and Chiang Mai University (Thailand) have proposed and developed innovative low-temperature plasma processes to activate the intrinsic catalytic properties of MOFs. In addition, they sustained the stability of MOFs for challenging catalysis of the water-gas shift reaction for hydrogen production which normally only occurs at high temperatures. 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.<\/p>\n
