Abstract

Vertically arranged manganese (III) oxide (Mn₂O₃) nanosheets (NSs) thin film was deposited on nickel (Ni) foil through low temperature hydrothermal method and utilized as smart working electrode for N-hydroxysuccinimide (NHS) chemical sensor. FESEM images revealed highly dense nanosheets structures which were vertically arranged on Ni foil. Grown Mn₂O₃-NSs displayed a typical cubic crystalline structure with good stoichiometric composition of elements. The electrochemical analysis of Mn₂O₃-NSs/Ni electrode demonstrated a high anodic peak which confirmed a high electrocatalytic activity towards NHS via fast charge transfer process. Mn₂O₃-NSs/Ni electrode based NHS chemical sensor showed significantly a high sensitivity = ~90μA.μM⁻¹cm⁻² and detection limit = ~3.6 μM with a correlation coefficient (R) of ~0.99088 and a short response time (10 s).
