Two-dimensional (2D) Janus thin films have received increasing attentions due to their unique asymmetric structures and fantastic applications. Herein, a macroscopic 2D freestanding Janus carbon
nanotube/gold nanoparticles (CNTs/AuNPs) hybrid ultrathin film is successfully constructed at the air/liquid
interface, using polydopamine modified unilaterally CNTs ultrathin network film
as asymmetrical 2D interfacial reactor for in-situ selective growth of AuNPs on the unilateral water-side of CNTs film. The resultant
macroscopic 2D freestanding Janus CNTs/AuNPs ultrathin film could be used
directly as electrode materials and modify stably electrode with improved stability and operation feasibility. More
importantly, the convenient and clean modification of Janus CNTs/AuNPs film on electrode
is favorable to the electrons transmission in the electrode and remarkably
improves the electrochemical sensitivity of GC, showing
the ability of really exerting asymmetrical functionality of Janus 2D materials
in a collaborative strategy.
