Ultrastrong Chemiluminescence Activity of Nanocarbon Materials after Ozonation and Their Effects on Different Chemiluminescent Systems

Ozonized nanocarbon materials with different dimensionalities, structures, and components exhibited significantly different chemiluminescence (CL) activities. The ozonation time and the weight ratio of hydroxyl carbon nanotubes (d approximate to 8 nm, hyCNTs-8) and graphene oxide (GO) strongly affected the CL activity of ozonized hybrids. Among GO, hyCNTs-8, and GO/hyCNTs-8, the GO/hyCNTs-8 hybrids exhibited the strongest CL-enhancing properties toward the luminol/H2O2 system, in contrast to previous reports. This study provides new understanding of the CL activity and CL-enhancing properties of nanocarbon materials in signal-enhanced analytical and biomedical fields.
