Abstract:

Residual metal impurities in the pristine carbon nanotubes (CNT) have been found to show an exceptional electrochemical and electro-catalytic properties. To quantify the impurities, sophisticated instrumental techniques and time consuming electrochemical methods have been adopted. Herein, we report, a new strategy for simple and quick detection of nickel impurity in pristine single walled carbon nanotube (SWCNT* Ni,* Ni= nickel impurity) as redox active nickel hexacyanoferrate hybrid (SWCNT* Ni-HCF) by potential cycling of the...
