Nanocomposite Materials for Green Energy Nanogeneration and Piezocatalysis

The quest for sustainable, greener energy through harvesting and heat-management technologies has recently developed a significant interest in new nanocomposite ceramics with large electromechanical, triboelectric, pyro- and piezocatalytic, and electrocaloric (EC) effects [1-4]. An overview of the large piezoelectric and triboelectric response in flexible ceramic nanocomposites exploiting enhanced multiferroic properties of lead-free BCZT and BaTiO3-based nanoparticles will be presented in this contribution, including flexible polymer composites' large energy harvesting potential [2]. The impact of filler's dielectric permittivity and size of nanoparticles on enhanced properties of flexible nanocomposites will be discussed [3]. In addition, the catalytic potential of ceramic nanoparticles in hydrogen evolution will be presented [4]. [1] Z. Kutnjak., B. Rozic, R.
