Abstract :
Current chemical methods of synthesis have shown limited success in the fabrication of
nanomaterials, which involves environmentally malignant chemicals. Environmental friendly synthesis
requires alternative solvents, and it is expected that the use of soft options of green approaches may
overcome these obstacles. Water, which is regarded as a benign solvent, has been used in the present
work for the preparation of platinum nanoparticles. The average particle diameter is in the range of
135 nm and particles are largely agglomerated. The advantages of preparing nanoparticles with this
method include ease, flexibility and cost effectiveness. The prospects of the process are bright, and the
technique could be extended to prepare many other important metal and metal oxide nanostructures.
