Summary In this study, we followed a facile method to grow well‐aligned PANI nanostructures on S‐doped reduced graphene oxide nanosheets (SPANI/S‐rGO) using hydrothermal method combined with soft template polymerization of aniline where naphthalene sulfonic acid is used as a dopant for PANI as well as the soft template. The effect of using different wt% of S‐rGO on the structural, morphology, and electrochemical performance of SPANI/S‐rGO composites has been evaluated. Supercapacitor fabricated using SPANI/S‐rGO10 (10 wt% of S‐rGO) composite based electrodes delivered a high specific capacitance of 347.5 F/g at a current density of 1 A/g in symmetrical cell design (the specific capacitance was calculated based on a single electrode). Only 11% of its initial capacitance is lost after 2500 cycles at a current density of 2 A/g. The enhanced performance is attributed to the optimum loading of S‐rGO in designing binary composite, well‐aligned growth of SPANI nanostructures on S‐rGO sheets, and synergistic effect of both S‐rGO and SPANI. The facile synthesized SPANI/S‐rGO composite electrode material with the aforementioned features is considered to be a promising candidate for a high‐performance supercapacitor.

The present work describes preparation of the reduced graphite oxide/nickel/palladium (rGO/Ni/Pd) composite and the examination of its basic electrochemical properties. The reduced graphite oxide was prepared by thermal reduction of graphite oxide beforehand obtained by electrochemical overoxidation of graphite in 8 M HClO4. In the second stage, Ni particles were electrodeposited onto rGO by the galvanostatic method. Finally, chemical deposition of palladium catalyst was performed to yield rGO/Ni/Pd composite. Transmission electron microscopy analysis (TEM) along with energy dispersive spectroscopy (EDS) technique has been used to determine the size as well as the distribution of Ni and Pd particles. The acquired electrochemical results revealed that rGO/Ni/Pd composite exhibits a good activity towards the processes of electrosorption of hydrogen. The highest calculated H/Pd atomic ratio for rGO/Ni/Pd electrode was equal 0.62. Electrocatalytic activity of the investigated material is also depicted by the reaction of methanol electrooxidation. Recorded current density of methanol electrooxidation was 15.04 A g−1 Pd.
