Abstract

Synthesis process engineering to alter size of nanoparticles has been a subject of constant exploration. Effect of reaction solvent on nanoparticle size evolution in wet chemistry based techniques has however been scarcely explored. This report illustrates interesting dependence of average size and size distribution of Pt nanoparticles on synergistic variations in reaction solvent type, precursor-to-surfactant molar ratio and reaction mixture heating rate. It is illustrated that using a suitable combination of above reaction variables Pt nanoparticles with average sizes from 3 to 21 nm and with a variety of size distribution characteristics can be synthesized.
