Syntheses, Characterizations and Applications of Zinc Peroxide Nanoparticles

The aim of this work was the synthesis of zinc peroxide nanoparticles via a high pressure impinging-jet reactor and via classical flask reaction. The nanoparticles were in situ stabilized and functionalized with six different stabilizer molecules: BMEP, o-PEA, citrate, glucose-1-phospahte, UDP-glucose and AOT. These molecules interacted with the particle surface via phosphate, carboxylate and sulfonate functions causing nanoparticle stabilization, while their other functional groups (methacrylates, amines, corboxylates, glucose functions) introduced new accessible functionalities. All synthesis approaches resulted in small and uniform nanoparticles with varying diameter between 2.1±0.6 and 14.4±5.2 nm depending on parameter like reaction time, stabilizer type and concentration. Further the investigations revealed that the nanoparticles were capable of releasing oxygen. This release could be triggered through elevated temperatures (T>190.0 °C) or through acidic aqueous environment (pH
