Nanostructured SnO2 encapsulated guar-gum hybrid nanocomposites for electrocatalytic determination of hydrazine

Synthesis of sol-gel derived tin dioxide (SnO2) nanoparticles grafted in to gaur gum (GG) organic-inorganic hybrid nanocomposite for determination of hydrazine (HZ). Under optimized experimental conditions, SnO2-GG/ITO electrode shows, linearity 2-22 mM, and detection limit 2.769 mM with high sensitivity of 5.72 μA cm− 2. The results clearly suggest that SnO2-GG nanocomposite electrode provides an attractive matrix for impregnation of metal-oxide nanoparticles and an improved sensing platform for the electrochemical studies.121
