Tin oxide nanoparticles modified by copper as novel catalysts for the luminol-H2O2 based chemiluminescence system.

In this study, SnO2 nanoparticles modified by copper were found to greatly enhance the chemiluminescence intensity of the luminol-H2O2 system for the first time. The developed approach was applied for the determination of H2O2 as a proof-of-concept example.
