One of the key bottlenecks of photocatalysis is the inability to translate the amazing properties of the catalyst (e.g. metal oxide, 2D materials etc.) to larger scales due to the inability to engineer them with control and to respond to the visible light. We have been pursuing approaches to scalably with plasma functionalisation and integration in to nano fibres etc, with plasma activated deposition of these materials with control of the interfaces between these layers. Good adhesion to surfaces of this building process could yield unique materials with tunable density, structure, morphology and properties and could lead to several interesting applications, for example waste water treatment, CO2 reduction etc.,
