Bisulfite induced chemiluminescence of g-C3N4 nanosheets and enhanced by metal ions†
Abstract
In this work, a novel chemiluminescence (CL) phenomenon was found: a g-C3N4 nanosheets suspension was mixed with NaHSO3 solution directly to produce luminescence, and the intensity of luminescence could be obviously enhanced by some metal ions, which was distinctly different from the phenomenon that Cu2+ ions can quench the fluorescence of g-C3N4 nanosheets as reported before.
