Feb 14: In a breakthrough development in Carbon Nanotubes Synthesis science, researchers at the Institute of Advanced Study in Science and Technology (IASST), an autonomous institute of the Department of Science and Technology (DST), Government of India, have unveiled a pioneering method for the synthesis of Carbon Nanotubes (CNTs) directly on glass substrates.
This innovative technique, conducted at a relatively low temperature of 750°C, employs sodium (Na) as a catalyst, eliminating the need for traditional transition metal catalysts like iron, cobalt, or nickel.
Key Highlights of method for the synthesis of Carbon Nanotubes (CNTs)
- Addressing Limitations in Conventional Synthesis Methods
- Traditional methods for synthesizing CNTs often require high temperatures exceeding 1000°C and involve the use of transition metal catalysts, which can pose challenges in terms of biocompatibility and cost.
- The novel approach circumvents these limitations by utilizing sodium as a catalyst and operating at a lower temperature, thus offering a cleaner and more sustainable synthesis process.
- Plasma Enhanced Chemical Vapour Deposition Technique (PECVD)
- The experiment leverages the Plasma Enhanced Chemical Vapour Deposition Technique (PECVD), where plasma is generated using a specially designed spiral-shaped fused hollow cathode source.
- This technique enables CNT synthesis on glass substrates under atmospheric pressure, providing a cost-effective alternative to conventional methods.
- Role of Sodium as Catalyst
- Through meticulous experimentation, researchers have identified sodium as the primary catalyst for initiating CNT growth.
- The presence of sodium in the as-grown CNTs allows for easy removal by washing with deionized water, ensuring the production of clean CNTs suitable for various applications.
- Potential Applications
- The synthesized CNTs hold immense potential for applications in energy research, biomedical fields, and optoelectronics.
- Their versatility makes them suitable for use in rechargeable batteries, flexible electronics, aerospace components, transparent electrodes, touch screens, supercapacitors, and medical devices.
- Patent Filed and Publication Link
- The groundbreaking research has led to the filing of a patent titled “A Process for Single-Step Synthesis of Carbon Nanotube on Glass Substrate” by Jyotisman Bora and Arup R. Pal.
- The findings have been published in a reputed scientific journal (Publication Link: https://doi.org/10.1016/j.apsusc.2023.158988).
