3D Porous Nanoarchitectures Derived from SnS/S-Doped Graphene Hybrid Nanosheets for Flexible All-Solid-State Supercapacitors

Researchers report the synthesis of novel 3D porous SnS/S-doped G hybrid nanoarchitectures (SnS/S-G HNAs) and their application for flexible, all-solid-state SCs. The synthesis is based on controllable thermal conversion of pre-synthesized mixed-phase SnS₂-SnS nanodisks that capped by oleylamine (OLA) molecules. By utilizing the promotion effect of SnS₂ component for carbonization of OLA molecules along with doping of S, and the phase transition and thermal stress to drive the assembly of in situ formed SnS/S-G hybrid nanosheets, the desirable 3D porous SnS/SG HNAs with the average pore size of about 3.9 nm can be easily obtained.
