Reduced graphene oxide doped tellurium nanotubes for high performance supercapacitor.

Supercapacitors have been achieving great interest in energy storage systems for the past couple of decades. Such devices with superior performance, mainly, depending on the material architecture of the electrodes. We report on the preparation of Tellurium nanotubes (Te-tubes diameter ∼100 nm and length ∼700 nm), with variable doping of conducting network reduced graphene oxide (rGO) to fabricate high-performance electrode characteristics of rGO @ Te.

Electrochemical performance of a self-assembled two-dimensional heterostructure of rGO/MoS/h-BN.

We report the preparation and electrochemical performance evaluation of a two-dimensional (2D) self-assembled heterostructure of graphene oxide (rGO), molybdenum disulphide (MoS), and hexagonal boron nitride (h-BN). In the present study, the rGO-MoS-h-BN (GMH) multi-layered GMH heterostructure is fabricated an chemical route. Based on material analysis, the composite consists of bond conformations of C-B-C, Mo-S, C-N, B-N, and Mo-C, indicating the layered stacks of rGO/h-BN/MoS.
