Abstract
Cubic phase zinc peroxide nanoparticles (ZnO2 NPs) with an average diameter of ca. 9-15Â nm have been synthesized via a fast nanosecond pulse laser ablation in liquid technique (PLAL), using H2O2 aqueous solution as the ablation media and a 532Â nm pulsed laser as the irradiation source and low-cost zinc powder as the solid target. Both the laser energy and ablation time potentially have a substantial influence on the formation of ZnO2 NPs. Due to its relatively high oxidation level as well as its hydrophilic wetting behavior, the as-synthesized ZnO2 NPs exhibit efficient photocatalytic degradation ability of Rhodamine B (RB) whilst remaining stable to photodegradation. The possible mechanisms of the photocatalytic behavior have been discussed in what follows.
