“…The k 1 and k 2 could be obtained from the slope and y-axis intercept respectively by drawing a linear plot of i/ν 1/2 versus ν 1/2 . 23,31,32,47,48 Figure 5c displayed the contributions of two different charge storage mechanisms at different scan rates (the contribution ratios of capacitive and diffusion-controlled capacities for c-CNC and c-PANi electrodes are displayed in Figure S7b,d, respectively). It is obvious that the capacitive contribution enlarged with the scan rate increasing and dominated the total current at scan rates above 0.6 mV s −1 .…”

A facile approach was developed to fabricate nitrogen/ oxygen (N/O) codoped carbon anodes by direct carbonization of cellulose nanocrystal/polyaniline (CNC/PANi) nanocomposites which were prepared by in situ growth of PANi onto CNCs. The carbonized CNC/PANi (c-CNC/PANi) anode delivered a high reversible capacity of 470 mAh g −1 at 200 mA g −1 over 100 cycles, which was almost two times higher than those for c-CNC. Moreover, it presented a better rate performance and higher Li-ion diffusion coefficient than c-CNC and c-PANi anodes. The c-CNC/PANi anode also exhibited a distinguished cycling stability with high Coulombic efficiency around 100% at a high current density of 1000 mA g −1 even after 2000 cycles. The significant improvement in the electrochemical performance should be attributed to the larger specific area and uniform N/O dual heteroatoms codoping which can provide sufficient active sites for Li ions storage and induce superior diffusion kinetics of Li ions. This work provided a facile strategy to fabricate N/O codoping carbon derived from the renewable resource of CNC, and it is expected to be a promising candidate anode material for Li-ion batteries application.

“…PANI-HCl displayed a nanofibrous structure with particle diameter of 30-50 nm, H 2 SO 4 produced a nanogranular structure with a particle diameter of 400 nm, and HNO 3 yielded a hollow, ball-like structure with a particle diameter of 1-1.4 um. On the other hand, Shen et al [24] synthesized PANI in the presence of sulfonic acids, and found that the prepared PANI exhibited a high degree of protonation, along with high conjugation, length, crystallinity, and electrical properties as compared to PANI prepared in common HCl medium. Recently, green synthesis of PANI was reported by Rahman et al [25], with a fibrous porous nanostructure network using sodium phytate as a dopant; the polymer exhibited a specific surface area of 230 m 2 /g.…”

Heavy metals represent one of the most important kinds of pollutants, causing serious threats to the ecological balance. Thus, their removal from aqueous solution is a major environmental concern worldwide. The process of adsorption—being very simple, economical, and effective—is widely applied for the decontamination of wastewaters from heavy metals. In this process, the adsorbent is the key factor affecting the performance; for this reason, significant efforts have been made to develop highly efficient and selective adsorbents with outstanding properties. This paper presents a detailed overview of the research on different methods of synthesis of nanocomposite materials based on the polymer polyaniline combined with nanomaterials, along with the influence of the synthesis method on their size, morphology, and properties. In addition, the study evaluates the adsorption efficiency of various developed nanocomposites for the adsorption of heavy metals from aqueous solution. From an economical and environmental point of view, the regeneration studies of the nanocomposites are also reported.

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.
