A facile continuous approach for the high throughput synthesis of functionalised 2D derived nanocomposites Conor Davids , Ioan-Alexandru Baragau, Sandra Dudley-McEvoy and Suela Kellici London South Bank University, UK Graphene has been synthesised in a variety of methods, however in general they are all a compromise between quality, scalability, and cost. 1 The reduction of graphene oxide has been shown to be a scalable and economical method to produce reduced graphene oxide (rGO), however the synthesis usually requires highly toxic reagents and the resulting rGO does not show the excellent properties of pristine graphene. 2 Here we report a continuous, green, and tuneable, single step synthesis of rGO from graphene oxide (GO) and the in-situ heteroatom doping, and metal nanoparticle decoration of rGO utilising our CHFS reactor previously reported. 3–5 Notably, the employment of CHFS has allowed the facile tuning and optimisation of properties of synthesised materials for a range of applications. We have successfully synthesised nitrogen and sulfur doped graphene as well as silver, copper and nickel decorated rGO. Products have been characterised by HR-TEM, XPS, Raman, XRD and BET surface area analysis, and have been shown to have high conductivities of 1.8x10 5 S/m, in selected cases. This work reports the facile synthesis of highly conductive graphene inks, whilst also illustrating the tunability of this method to design and synthesise a portfolio of functionalised materials for a range of applications mainly catalysis and energy related including batteries and supercapacitors.
