The present manuscript has synthesized the innovative nanocomposite of tungsten decorated reduced graphene oxide (TGO) based FeNi codoped MnO2 (TGO-3 % FeNi-MnO2) which has better supercapacitor performance than the tungsten carbide (TC) MXene-based nanocomposite sample (TC-3 % FeNi-MnO2). The first motive of the manuscript is to manufacture lower-cost materials with better properties with higher stability. Nowadays, worldwide researchers are focusing on MXene materials and reporting the best smart material for multiple applications but the present manuscript has done an innovative study and found that the graphene-based materials have good properties with higher stability like MXene samples. The prepared nanocomposite samples have been characterized by XRD, FE-SEM, BET, XPS, Fluorescence spectroscopy, and cyclic voltammetry. X-ray diffraction (XRD) investigation demonstrated that mixed phases of tetragonal α-MnO2 and cubic α-Mn2O3 were observed. The nanocomposite of tungsten decorated reduced graphene oxide-based FeNi codoped MnO2 has a nanorod-like morphology which was better than all synthesized samples. The higher capacitance found for the tungsten decorated reduced graphene oxide-based Fe-Ni codoped MnO2 sample is 883 F g−1. The impact of the surface area (317.42 m2/g), defects, and structural parameters on capacitance enhancement was studied in detail. The TGO-3 % FeNi-MnO2 sample has higher surface defects which was attributed by XPS and fluorescence spectroscopy. © 2025 Elsevier Masson SAS

Serious climate changes and energy-related environmental problems are currently critical issues in the world. In order to reduce carbon emissions and save our environment, renewable energy harvesting technologies will serve as a key solution in the near future. Among them, triboelectric nanogenerators (TENGs), which is one of the most promising mechanical energy harvesters by means of contact electrification phenomenon, are explosively developing due to abundant wasting mechanical energy sources and a number of superior advantages in a wide availability and selection of materials, relatively simple device configurations, and low-cost processing. Significant experimental and theoretical efforts have been achieved toward understanding fundamental behaviors and a wide range of demonstrations since its report in 2012. As a result, considerable technological advancement has been exhibited and it advances the timeline of achievement in the proposed roadmap. Now, the technology has reached the stage of prototype development with verification of performance beyond the lab scale environment toward its commercialization. In this review, distinguished authors in the world worked together to summarize the state of the art in theory, materials, devices, systems, circuits, and applications in TENG fields. The great research achievements of researchers in this field around the world over the past decade are expected to play a major role in coming to fruition of unexpectedly accelerated technological advances over the next decade. © 2023 The Authors.
