Platinum Nanoparticles: Synthesis Strategies and Applications

Abstract

Plantinum nanoparticles (Pt NPs) have huge potential as heterogeneous catalyst, chemiresistor coating material, nanomedicine, nanosensor, and electronic components along with various other industrial applications. Physical, chemical as well as biological methods are used for the synthesis of plantinum NPs. Physical methods depend upon the physical phenomenon for Pt NPs synthesis. Chemical methods involve one or other chemical reactions to prepare Pt NPs. Biological methods are preferred over other methods. Among all biological sources, use of plant extracts for Pt NPs synthesis is safe and cost-effective. Pt NPs have application in catalysis, electronics, nanodiagnosis and nanomedicine. Synthesis of diverse Pt NPs using different plant bioresource may be more useful for various in vivo applications in future.
