Liquid exfoliation of quasi-2D nanosheets for use as efficient visible-light photocatalysts

Two-dimensional (2D) materials have received significant scientific attention due to their exceptional properties. The most well-known of this class of nanomaterial is graphene, however, there are numerous mono- and few-layer 2D materials which have the potential to transform existing and future technologies across a wide range of sectors. Applications include opto-electronics, semiconductors, biomedical sensors, tissue engineering, drug delivery, and energy conversion and storage. Semi-conductors such as MoS2, g-C3N4, and various 2D/2D heterostructures also function as photocatalysts that can perform pollution degradation and solar fuel production using only visible light. If realised on a global scale, these materials could deliver sustainable clean water and hydrogen fuel. This would have a major impact on resource use globally, and in particular for arid regions where water quality issues and abundant solar radiation co-exist. It is, therefore, imperative that these exciting materials can be exploited on a large scale to address the global challenges that society faces.

Production is a key area that requires attention. Liquid exfoliation is one promising approach, however, the performance is typically poor (a few percent yield). The aim of this research project is to develop new insights on 2D nanosheet production, using a combination of advanced multiphase numerical and experimental fluid dynamics techniques, while also revealing a critical understanding of the relationship between the synthesised nanosheet structures and their photocatalytic performance. We are looking to recruit an excellent graduate from a relevant discipline (i.e. Chemical/Mechanical/Materials Engineering or closely related).
