Article Synopsis
- 1,10-Phenanthroline (Phen) is a widely used ligand for transition metal ions but is difficult to oxidize in water due to its high electro-oxidation potential.
- Researchers reported a successful oxidation of Phen into 1,10-phenanthroline-5,6-dione (Phen-dione) using a modified glassy carbon electrode with multiwalled carbon nanotubes (MWCNT), facilitating effective copper ion recognition.
- The structure of the oxidized product was confirmed through various characterization techniques, establishing that Phen-dione complexed with copper ions through its nitrogen atoms.
A new biomimetic functional system having an impure multiwalled carbon nanotube (MWCNT-Fe)-chitosan biopolymer (H2N-CHIT) chemically modified glassy carbon electrode (GCE/[MWCNT-Fe:H2N-CHIT]) has been developed and demonstrated efficient hydrogen peroxide electrocatalytic and electrochemical sensing applications in pH 7 phosphate buffer solution (PBS). The hybrid system showed a stable and well-defined surface confined redox peak at an apparent electrode potential, E°'=-0.22 V versus Ag/AgCl with surface excess value 13.
