Harnessing Energy

Intense research into cutting-edge energy harvesting technology has been fueled by the persistent pursuit of sustainable energy alternatives. Organic–inorganic hybrid nanomaterials have become a promising shift in this pursuit. These hybrid nanomaterials unlock previously unheard-of potential for effective energy conversion and storage by combining the advantages of organic and inorganic components in a synergistic way. Organic–inorganic hybrid nanomaterials provide improved optical, electrical, and thermal capabilities. These unique features make it possible to create high-performance energy harvesting devices that can transform a variety of energy sources, including thermal, electromagnetic, vibrational, and solar radiation. This chapter highlights the advantages of employing HNGs in self-powered applications, focusing on the enormous potential of organic–inorganic hybrid nanomaterials in energy harvesting. The material part discusses four categories: 2D materials, porous materials, ferroelectric materials, and natural materials. A separate section is dedicated to analyze hybrid nanogenerators, which includes combination of different mechanisms like triboelectric, piezoelectric, pyroelectric, and electromagnetic nanogenerators. It also gives a brief review of recent advances in Triboelectric Nanogenerator (TENG)-based self-powered sensors and their prospective applications in a variety of disciplines, including environmental monitoring, healthcare, wearable technology, IoT, and smart cities. We examine the synthesis, characteristics, and uses of these hybrid nanomaterials, remarkable advantages, challenges, and future prospects. By utilizing these cutting-edge materials, we can transform the renewable energy landscape and open the door for efficient, self-sufficient, and sustainable energy systems.
