Ordered Mesoporous NiCo2O4 Nanospheres as a Novel Electrocatalyst Platform for 1-Naphthol and 2-Naphthol Individual Sensing Application
Source abstract
Abstract
The novel ordered mesoporous NiCo 2 O 4 (meso-NiCo 2 O 4 ) nanospheres were synthesized by the nanocasting strategy followed by a calcination process for 2-naphthol (2-NAP) and 1-naphthol (1-NAP) individual sensing application. The as-obtained meso-NiCo 2 O 4 material possesses mesoporous structure in spinel crystalline type with a larger specific surface area than other structures. The meso-NiCo 2 O 4 -modified carbon paste electrode exhibited excellent electrocatalytic performance for NAP detection by amperometry measurement. The fabricated sensor of 2-NAP and 1-NAP has a wide linear detection range (0.02–300 and 0.02–20 μM) with high sensitivity (1.822 and 1.510 μA μM –1 cm –2 ) and low limit of detection (0.007 and 0.007 μM), respectively. In addition, the NAP sensors possess excellent reproducibility, stability, and selectivity.
