This chapter examines the latest developments in metal oxide
nanocomposites and their uses in energy harvesting devices. The chapter begins with a
brief overview of metal oxide nanocomposites, emphasizing their makeup and
importance in improving energy conversion processes, including thermoelectric, solar,
and piezoelectric ones. A thorough review of current developments exposes cuttingedge synthesis methods and the advantages of nanostructuring, which enhance the
performance and characteristics of materials. Several forms of metal oxide
nanocomposites are classified in this chapter, emphasizing the widely used materials
such as ZnO, TiO2
, and SnO2
, along with novel hybrid systems that blend metal oxides
with polymers or other materials for improved performance. A detailed discussion is
also included regarding the fabrication processes and characterization methodologies
that evaluate the performance of these nanocomposites, highlighting their potential
applications in solar energy, waste heat recovery systems, and wearable technology.
Additionally, the drawbacks and restrictions of metal oxide nanocomposites, including
scalability and material stability, are also addressed in this chapter. Emerging materials
and their potential integration into smart energy systems are highlighted below, along
with future trends and research directions. A case study shows its practical applications
and is included in the chapter's conclusion, along with consideration of these materials'
sustainability and effects on the environment in the current situation. By comparing
metal oxide nanocomposites with other nanomaterials, we highlight the advantages of
these materials as well as potential market trends. This comprehensive study thus aims
to shed light on the ground-breaking significance that metal oxide nanocomposites play
in the search for durable and efficient energy harvesting technologies.
