A facile ternary nanocomposite comprising of polyaniline, titanium dioxide, polypyrrole, that is, PANI‐TiO2‐PPy was synthesized by in‐situ chemical oxidative polymerization method and fabricated as an active electrode material for supercapacitor applications. The phase, morphology, chemical composition, electronic states and thermal behavior of PANI‐TiO2‐PPy were analyzed using XRD, FESEM/EDAX, FTIR, XPS, and TGA techniques. CV profile of PANI‐TiO2‐PPy electrode exhibits the highest specific capacitance (600 F g−1) at 1 mV/s in 1 M KOH electrolyte, which is higher than the PANI (31 F g−1), PPy (120 F g−1), and TiO2 (398 F g−1) electrodes. The charge storage mechanism of PANI‐TiO2‐PPy electrode was also explored in 1 M H2SO4 and 1 M Na2SO4 electrolytes; wherein the capacitive behavior of ternary electrode was found to be superior in alkaline electrolyte compared to acidic and neutral electrolytes. From GCD, the ternary electrode exhibited the longest charge/discharge curve when compared to unary electrodes, which affirms the improved energy storage capacity of PANI‐TiO2‐PPy. The lower ESR value (0.90 Ω) exhibited by ternary electrode in comparison with PANI (1.75 Ω), PPy (1.59 Ω), and TiO2 (2.11 Ω) and 92% of capacitive retention after 2500 charge/discharge cycles suggest that PANI‐TiO2‐PPy could be a suitable active electrode for supercapacitors.

Purpose This paper aims to investigation of processes for Pb2+ elimination from water/wastewater as a significant public health issue in many parts of world. The removal of Pb2+ ions by various nanocomposites has been explained from water/wastewaters. ZnO-based nanocomposites, as eco-friendly nanoparticles with unique physicochemical properties, have received increased attention to remove Pb2+ ions from water/wastewaters. Design/methodology/approach In this review, different ZnO-based nanocomposites were reviewed for their application in the removal of Pb2+ ions from the aqueous solution, typically for wastewater treatment using methodology, such as adsorption. This review focused on the ZnO-based nanocomposites for removing Pb2+ ions from water and wastewaters systems. Findings The ZnO-based nanocomposite was prepared by different methods, such as electrospinning, hydrothermal/alkali hydrothermal, direct precipitation and polymerization. Depending on the preparation method, various types of ZnO-based nanocomposites like ZnO-metal (Cu/ZnO, ZnO/ZnS, ZnO/Fe), ZnO-nonmetal (PVA/ZnO, Talc/ZnO) and ZnO-metal/nonmetal (ZnO/Na-Y zeolite) were obtained with different morphologies. The effects of operational parameters and adsorption mechanisms were discussed in the review. Research limitations/implications The findings may be greatly useful in the application of the ZnO-based nanocomposite in the fields of organic and inorganic pollutants adsorption. Practical implications The present study is novel, because it investigated the morphological and structural properties of the synthesized ZnO-based nanocomposite using different methods and studied the capability of green-synthesized ZnO-based nanocomposite to remove Pb2+ ions as water contaminants. Social implications The current review can be used for the development of environmental pollution control measures. Originality/value This paper reviews the rapidly developing field of nanocomposite technology.
