Abstract: © 2016 Elsevier B.V. The synergistic effect of oxygen releasing and oxidizing power of calcium peroxide (CaO2) provides considerable advantages to environmental issues. In this research, a novel productive method to synthesize high-purity nanoparticle was reported. Ca(NO3)2was used as an effective precursor under mild conditions. High-purity CaO2with nanosized spherical particle was observed. Disinfection effect of the CaO2powders was investigated using Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). Surprisingly, photoactivity of CaO2was discovered. The CaO2exhibited intriguing photoactivity on dye oxidation and reduction under visible light. This method produces high-purity nanoparticulate CaO2for pilot-scale testing.
