Recent Development of Morphology‐Controlled Hybrid Nanomaterials for Triboelectric Nanogenerator: A Review

Abstract

Being cognizant of modern electronic devices, the scientists are continuing to investigate renewable green‐energy resources for a decade. Amid different energy harvesting systems, the triboelectric nanogenerators (TENGs) have been found to be the most promising mechanical harvesting technology and have drawn attention to generate electrical energy. Thanks to its instant output power, choice to opt for wide‐ranging materials, low maintenance cost, easy fabrication process and environmentally friendly nature. Due to numerous working modes of TENGs, it is dedicated to desired application at ambient conditions. In this review, an advance correlation of TENGs have been explained based on the variety of nanostructures, including 0D, 1D, 2D, 3D, metal organic frameworks (MOFs), coordination polymers (CPs), covalent organic frameworks (COFs), and perovskite materials. Moreover, an overview of previous and current perspectives of various nanomaterials, synthesis, fabrication and their applications in potential fields have been discussed in detail.

“…Due to that, material FOM leads to a new generation of tribo materials including 2D materials, ferroelectric materials, and MOFs/COFs. [24][25][26] MOFs are crystalline materials with highly ordered structures combining a metal ion or cluster with organic ligands through coordination bonds. This unique structure leads to high porosity, high surface area, chemical reactivity and tunability.…”
