Development of a novel and efficient H2O2 sensor by simple modification of a screen printed Au electrode with Ru nanoparticle loaded functionalized mesoporous SBA15

Abstract

A novel and efficient electrochemical sensor has been developed to quantitatively measure H2O2 concentration by cyclic voltammetry. The sensor was prepared by modifying screen printed gold electrodes by ruthenium nanoparticle (Ru nanoparticle) loaded thiol functionalized mesoporous SBA15 (Ru@SBA15-SH) which was prepared by three simple steps. During measurement H2O2 electrochemically interacted with Ru nanoparticles and was channelled appropriately through the mesoporous structure of SBA15. The developed sensor showed a wide detection range with high sensitivity, durability and reproducibility. Furthermore, a very low limit of detection was reported by the sensor (0.42 μM (∼0.0142 ppm)), which was much lower than the permissible exposure limit.
