Functionalisation of graphite and thermally reduced graphene oxide with bis-hydrazone copper(i) nitrate salt

Abstract

The solvothermal functionalization of graphite and thermally reduced graphene oxide (TRGO) using a bis-hydrazone copper(I) complex is demonstrated. This treatment resulted in a remarkable 328% increase in the BET specific surface area of graphite, reaching 374 m² g⁻¹, while the surface area of TRGO remained unchanged. The hybrid composites show promise as potential components for gas sensors.
