Cellulose‐Templated Nanomaterials for Nanogenerators and Self‐Powered Sensors

Abstract

Energy crisis inspires the development of renewable and clean energy sources, along with related applications such as nanogenerators and self‐powered devices. Balancing high performance and environmental sustainability in advanced material innovation is a challenging task. Addressing the global challenges of sustainable development and carbon neutrality lead to increased interest in biopolymer research. Nanocellulose materials, derived from biopolymers, demonstrate potential as template candidates for advanced materials, due to their unique properties, including high strength, high surface area, controllable pore structures and high‐water retention. In recent years, cellulose‐templated nanomaterials enable delicate nano‐/microscale structural construction, thus promoting developments in the field of nanogenerators and self‐powered sensors. However, there is still a limited number of reviews focused on cellulose‐templated nanomaterials for applications in nanogenerators and self‐powered sensors. This review aims to fill this research gap by introducing various cellulose‐templated nanomaterials and providing a detailed analysis of their fashionable applications in nanogenerators and self‐powered sensors. The goal is to present cellulose‐templated nanomaterials as highly promising template and guest materials for templating technologies, offering sustainable nano‐/microscale control over advanced materials for the foreseeable future. This potential is promising for new applications in the fields of nanogenerators and self‐powered sensors.
