Properties of nanosheets of 2D-borocarbonitrides related to energy devices, transistors and other areas

We have prepared borocarbonitrides of various compositions with extended sheet morphology, by the reaction of few-layer graphene with boric acid and urea at 900°C and characterized them in detail. Supercapacitor performance of the borocarbonitrides has been studied in detail, the composition containing more pyridinc nitrogen exhibiting a specific capacitance of 306F/g at 0.2A/g. This composition also shows good oxygen reduction reaction (ORR) activity with an electron transfer number close to 4. The extended sheet structures of the B x C y N z samples has enabled us to fabricate field-effect transistors. These materials also show reasonable UV photoresponse.
