Composites of carbons with metal oxides and metal sulfides have attracted a lot of interest
as materials for energy conversion and storage applications. Herein, we report on novel N,O-doped
carbon/ZnO/ZnS and N,O-doped carbon/ZnO composites (generally named C-(MOF-5/PANI)),
synthesized by the carbonization of metal–organic framework MOF-5/polyaniline (PANI) composites.
The produced C-(MOF-5/PANI)s are comprehensively characterized in terms of composition,
molecular and crystalline structure, morphology, electrical conductivity, surface area, and electrochemical
behavior. The composition and properties of C-(MOF-5/PANI) composites are dictated by
the composition of MOF-5/PANI precursors and the form of PANI (conducting emeraldine salt (ES)
or nonconducting emeraldine base). The ZnS phase is formed only with the PANI-ES form due to
S-containing counter-ions. XRPD revealed that ZnO and ZnS existed as pure wurtzite crystalline
phases. PANI and MOF-5 acted synergistically to produ...ce C-(MOF-5/PANI)s with high SBET (up to
609 m2 g−1), electrical conductivity (up to 0.24 S cm−1), and specific capacitance, Cspec, (up to 238.2 F
g−1 at 10 mV s−1). Values of Cspec commensurated with N content in C-(MOF-5/PANI) composites (1–
10 wt.%) and overcame Cspec of carbonized individual components PANI and MOF-5. By acid etching
treatment of C-(MOF-5/PANI), SBET and Cspec increased to 1148 m2 g−1 and 341 F g−1, respectively.
The developed composites represent promising electrode materials for supercapacitors.
