| Summary: | © 2016 Elsevier B.V. The synergistic effect of oxygen releasing and oxidizing power of calcium peroxide (CaO 2 ) provides considerable advantages to environmental issues. In this research, a novel productive method to synthesize high-purity nanoparticle was reported. Ca(NO 3 ) 2 was used as an effective precursor under mild conditions. High-purity CaO 2 with nanosized spherical particle was observed. Disinfection effect of the CaO 2 powders was investigated using Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). Surprisingly, photoactivity of CaO 2 was discovered. The CaO 2 exhibited intriguing photoactivity on dye oxidation and reduction under visible light. This method produces high-purity nanoparticulate CaO 2 for pilot-scale testing. |
