Characterization and Photocatalytic Properties of ZnO Tetrapods Synthesized by High-Temperature Pyrolysis
摘要
This work presents the structural and morphological characterization and the results of studies of the luminescence and photocatalytic properties of ZnO tetrapods synthesized by high-temperature pyrolysis. It was demonstrated that the morphology and structural parameters of ZnO tetrapods are defined by the location in the synthesis zone. All samples are characterized by pseudo-three-dimensional morphology of tetrapods. The correlation was found between the luminescence properties and photocatalytic activity of tetrapods. The highest photodegradation rates of methylene blue under UV radiation were demonstrated by ZnO tetrapods grown in the zones closest to and farthest from the air-inlet window (the rate constants were 54 × 10–3 and 50 × 10–3 min–1, respectively).
