| Abstract: |
Nano-CoPcS/TiO2 were synthesized by the dipping method and further characterized by X-ray diffraction spectrogram and UV-vis spectra. We found that nano-CoPcS/TiO2 enhanced the chemiluminescene(CL) intensity of a luminol system. Sonoluminescence and optically stimulated luminescence were equivalent; however with the addition of nano-material into the luminol solution， sonoluminescence intensity was higher than optically stimulated luminescence intensity. Our data suggest that the optimized conditions for nano-CoPcS/TiO2 catalyzed CL of luminol was at pH 12.5, under the concentration of 1.2 mM luminol and 0.3 mg•mL-1 solid-containing content of nano-CoPcS/TiO2 solution. The possible reaction mechanisms were also elaborated on. Chemiluminesence of luminol catalyzed by nano-CoPcS/TiO2 resulted from the absorption effect of the nano-CoPcS/TiO2 surface to luminol, the formation of nano active species and minimal cavitation bubble. |
