Functionalization of indium tin oxide electrode with both of dendrimer-encapsulated Pt nanoparticles and chemically converted graphenes for enhanced electrochemiluminescence of luminol/H2O2

Abstract: Here, we report highly enhanced electrochemiluminescence (ECL) of luminol in the presence of H2O2 on indium tin oxides (ITOs) modified with both of dendrimer-encapsulated Pt nanoparticles (Pt DENs) and chemically converted graphenes (CCGs). The ITO electrodes were electrochemically modified with size-monodisperse Pt DENs via electrooxidative grafting of the terminal amines of the dendrimers encapsulating Pt nanoparticles. The Pt DEN-modified ITOs were then decorated with CCG sheets via electrostatic attachment… Show more

“…6.7% over the entire visible region from 400 to 800 nm compared to that of unmodified ITO, which represented the preserved optical transparency of ITOs even after the electrochemical deposition of G6‐OHPt on ITO surfaces. This is an important feature for analytical applications of ECL because it is recommended that ITO electrodes are optically transparent for the efficient detection of ECL signals 23–25 …”

“…For increasing the ECL efficiency of luminol/H 2 O 2 in neutral media, the utilizing of the electrocatalytic property of a nanomaterial is a promising method. By decorating nanomaterials, such as metal nanoparticles, metallic oxide nanoparticles, and carbon-based nanomaterials, on the working electrode, ECL of luminol/H 2 O 2 can be easily promoted by the electrocatalytic oxidation of luminol and H 2 O 2 , thus facilitating the generation of ECL. More importantly, the nanomaterial-modified electrode may favor the electrocatalytic reduction of H 2 O 2 to HO • and provides another pathway to generate ECL of luminol/H 2 O 2 by sweeping the potential toward negative direction. , In contrast with anodic luminol/H 2 O 2 ECL, such cathodic luminol/H 2 O 2 ECL has a simpler mechanism as only H 2 O 2 is reduced to trigger the ECL reactions between HO • and the deprotonated luminol.…”
