Synthesis of Pt-MWCNT Nano Composite in Trioctylmethyl Ammonium Hydrogen Phthalate (TOMAHP) Ionic Liquid Using Ultrasonic Cavitation

Abstract

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 technique. 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.
