Hydrothermal synthesis of an SnO₂–rGO nanocomposite using tea extract as a reducing agent for daylight-driven photocatalyst and supercapacitors

Abstract

In this study, SnO2-rGO nanocomposites (NCs) were synthesized by hydrothermal method using tea extract as a reducing agent. The composition and structural properties of the nanocomposite were analysed using different...

Ternary Fe3O4/reduced graphene oxide/phytic acid doped polyaniline hybrid based supercapacitive electrode with high capacitance retention and good cycling stability

“…In general, pseudocapacitors display a higher C s and energy density than those of EDLCs. 17 Among the diverse range of pseudocapacitors, polyaniline (PANI) based pseudocapacitors have gained special attention for their high theoretical capacitance, easy synthesis, and desirable chemical stability. [18][19][20] However, pure PANI usually suffers from poor rate performance and weak cycling stability owing to deterioration of the structures caused by large volume expansion/contraction during the repeated doping/dedoping process.…”
