Intensification of the electrochemiluminescence of luminol on hollow TiO2 nanoshell-modified indium tin oxide electrodes

Synthesized hollow titania nano-shell, after immobilized onto indium tin oxide glass to act as working electrode, intensify the electrochemiluminescence (ECL) of luminol. The ECL got a 150 times multiplication than on bare electrode. It is also closely related to the content of reactive oxygen species in solution, got a detection limit for H2O2 at the level of 10−10 mol/L.
