Abstract
Nanoparticles have emerged as highly promising catalysts due to their unique physical and chemical properties arising from their small size and high surface area–to–volume ratio. This review delves into the diverse applications of nanoparticles as catalysts in various chemical reactions. A key advantage lies in their substantial surface area–to–volume ratio, facilitation, enhanced accessibility of reactants, and heightened interaction with the catalyst surface. This distinctive characteristic results in improved catalytic activity and efficiency. Additionally, size-dependent properties, such as surface plasmon resonance and quantum confinement effects, offer opportunities for tailoring catalytic behavior. Despite their immense potential, challenges such as synthesis, stability, toxicity, aggregation, and recyclability require attention. Future research should prioritize scalable and sustainable synthesis methods, improve catalyst stability under harsh conditions, and ensure safe handling and disposal. This review provides an overview of the role of nanoparticles as catalysts and highlights their significance in various fields, highlighting their exceptional performance, versatility, and environmental benefits.
Keywords: Nanoparticles, catalyst, environmental remediation, green technology, size dependent properties, catalytic behavior.
