Abstract
A novel methyl jasmonate (MeJA) sensor based on phosphotungstic acid/graphene oxide (PTA/GO) nanohybrid was developed by layer-by-layer assembling on a pre-anodized graphite electrode. Owing to the synergistic effect of the good conductivity, high surface area of GO and the solid super-acidity of PTA, the MeJA electrochemical sensor exhibited excellent electrocatalytic activity for the oxidation of alkylene group in MeJA, displaying as a wide linear response from 5.0 × 10−7 to 8.0 × 10−5 M and a low detection limit of 2.0 × 10−7 M in 0.1 M HClO4 solution.
