Designing mixed matrix structures has many advantages in separation, adsorption and catalytic processes. For instance, building inorganic mixed matrix membranes (MMM) such as carbon and stainless steel hollow fibres conferred superior mechanical properties whilst separating greenhouse gases. Similarly, alumina carbon MMM prepared via a vacuum method conferred the unusual effect of vacuum film etching, thus improving water fluxes in desalination processes. In another example, MMM containing perovskites and catalytic cooper phases achieved recently the best ever oxygen fluxes from air separation. Mixed matrix materials have also showed improved performance in catalysis and adsorption. Incorporating graphene oxides into metal oxide catalysts resulted in enhanced kinetic activity related to the degradation of dyes. Of particular importance is the sacrificial role played by graphene oxide is stabilising the active sites of iron oxides in the heterogeneous Fenton-like reaction is discussed. Again, graphene incorporation into an amine functionalised mesoporous silica increased CO2 sorption capacity, an important technology to abate greenhouse gases. This presentation will cover conceptual ideas and preparation methods together with ensuing discussions on mixed matrix structures.
