Poly (3‐methylthiophene) (P3MT) was modified by nickel oxide (NiO) and nickel sulfide (NiS) nanoparticles to enhance its electrochemical performance. The surface influence, crystalline structure, and electrochemical performance of the P3MT/NiO/NiS material were characterized and compared with that of pristine P3MT. It is found that surface modification can improve the structural stability of P3MT without decreasing its available specific capacitance. The electrochemical properties of synthesized P3MT/NiO/NiS electrode were evaluated using cyclic voltammetry and alternating current impedance techniques in 3 M KOH electrolyte. Specific capacitances of 253, 764, 932, and 1434 F g−1 were obtained for P3MT, P3MT/NiO, P3MT/NiS, and P3MT/NiO/NiS, respectively at 5 A g−1. This improvement is attributed to the synergistic effect of Ni2+ ions in the P3MT/NiO/NiS electrode material. The P3MT/NiO/NiS electrode in KOH has average specific energy and specific power densities of 1032 Wh kg−1 and 6192 W/kg, respectively. Only 2% of the capacitance's initial value is lost after 10,000 cycles. The resulting P3MT/NiO/NiS nanocomposite had very stable and porous layered structures. This work demonstrates that P3MT/NiO/NiS nanomaterials exhibit good structural stability and electrochemical performance, and are good material for supercapacitor applications.Highlights The P3MT/NiO/NiS nanocomposite is fabricated and characterized as supercapacitor electrode. The incorporation of NiO/NiS in the poly (3‐methylthiophene) has improved the electrochemical performance. The P3MT/NiO/NiS electrodes retained 98% of their specific capacitance after 10,000 cycles. The P3MT/NiO/NiS nanocomposite electrode showed specific capacitance of 1434 F g−1 at 5 A g−1. The stability of the nanocomposite was enhanced without altering its morphology and chemical structure.

“…The peaks at 3441.97 cm -1 and 1631.77 cm -1 are assigned to surface hydroxyl and the band at 1384.31 cm -1 is due to OH bending [32,35]. The peak at 532 cm -1 indicates the presence of oxides stretching and bending vibrations in PbO, 684 cm -1 is attributed to Pb-O vibrations while the characteristic absorption peak observed at 458.57 cm −1 is assigned to the stretching band of Pb-O [21,36]. The peak observed at 684 cm -1 and a few low-intensity peaks are indications of Cd-O stretching and bending vibrations [35][36][37].…”

“…Synthesis, optical properties and efficient photocatalytic activity of CdO/ZnO hybrid nanocomposite was under taken by Reddy et al [20]. Flake-like CuMn2O4 (Copper manganite) Nanoparticles (NPs) were prepared by the Co-precipitation method and the energy band gap was found to be 2.54 eV [21]. The photocatalytic degradation efficiencies were found to be 86% and 92% for methylene blue and malachite green respectively.…”

Present work comprises of fabrication of the novel Pb3CdO7 ternary oxide composite from the corresponding precursors using a co-precipitation approach and calcined. The as-prepared material is then characterized by FTIR, FE-SEM, XPS, EDX, XRD, HR-TEM etc. analytical methods. Based on UV-Vis-NIR spectroscopy, the composite's direct energy band gap is determined to be 5.23 eV, which makes it an effective photocatalyst. The prepared photocatalyst is found to degrade Azure-A dye with an efficiency of up to 94.87%. Scavenger study suggests the participation of active free radicals O2•- (superoxide anion radical) as the responsible species in breakdown of the dye molecules. The operating parameters are controlled to maximize the photodegradation and a kinetic study is carried out. Used photocatalyst is recycled and is found to work at the same pace for up to five cycles.
