Description |
Technical advancement in the field of ultra-small sensors and devices demands the development of novel
micro- or nano-based architectures. Here we report the design and assembly of cross-linked three
dimensional graphene nanoribbons (3D GNRs) using solution based covalent binding of individual 2D
GNRs and demonstrate its electrochemical application as a 3D electrode. The enhanced performance of
3D GNRs over individual 2D GNRs is established using standard redox probes – [Ru(NH3)6]3+/2+,
[Fe(CN)6]3−/4− and important bio-analytes – dopamine and ascorbic acid. 3D GNRs are found to have
high double layer capacitance (2482 μF cm−2) and faster electron transfer kinetics; their exceptional
electrocatalytic activity towards the oxygen reduction reaction is indicative of their potential over a wide
range of electrochemical applications. Moreover, this study opens a new platform for the design of novel
point-of-care devices and electrodes for energy devices
