제목 Preparation of magnetically separatable TiO2 coated NiFe2O4 photocatalyst Using ultrasonic spray pyrolysis
초록 Submicron size NiFe2O4 particle was prepared by ultrasonic spray pyrolysis and TiO2 nano particle was coated continuously. NiFe2O4 particle has a good ferromagnetic property and there are no impurities between TiO2 and NiFe2O4 under the high reaction temperatures. The methylene blue photodecomposition was used for the measurement of TiO2 coated NiFe2O4 photoactivity. TiO2 coated NiFe2O4 photocatalyst showed good photoactivity compared with commercial photocatalyst (Degussa P-25) and TiO2-SiO2 layer coated NiFe2O4 particle had more enhanced the photoactivity. In case of TiO2-SiO2 layer coated NiFe2O4, there was no difference before and after washing test and there was no photoactivity decreasing during the recycled photoactivity test.
