Background: Synthesis of nano composite materials is very important topic in recent
times for its wide application as a catalyst in various chemical processes. Among various nano composite
platinum-mutliwall Carbone Nano Tubes is of particular interest in recent past due to its
unique application in methanol fuel cell as a catalyst. Now the challenge is to make a chemical process
for definite size and shape selective platinum-mutliwall Carbone Nano Tubes catalyst/composite
with well distribution and easy scale up.
Methods: The aim of the present work is to develop a chemical process for synthesis of platinum-
Mutliwall Carbone Nano Tubes nano catalyst/composite with very low size (1-3nm) using reduction
of Pt4+ and subsequently deposition to the Mutliwall Carbone Nano Tubes surface using ultrasound
Results: The platinum nano materials synthesized in trioctylmethyl ammonium hydrogen phthalate is
characterized using TEM technique. The results show that the particle size of platinum nano are in
the range of 1-3 nm. The platinum-mutliwall Carbone Nano Tubes catalyst/composite prepared using
ultrasound technique does not change the particle size of the platinum nano particles. The distribution
of platinum nano on Functionalized Mutliwall Carbone Nano Tubes surface is uniform compared to
Non-functionalized Mutliwall Carbone Nano Tubes.
Conclusion: The preparation of platinum-mutliwall Carbone Nano Tubes nano composite with very
low size of platinum (1-3nm) is achieved in trioctylmethyl ammonium hydrogen phthalate as functionalized
ionic liquid in presence of ultrasound.
