CaIn2O4 semiconductors were synthesized by a solid-state reaction and characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), and UV-visible spectrometer. The photocatalytic activity was evaluated by the photodegradation methylene blue under visible light irradiation. Furthermore, Research the CaIn2O4 Photocatalytic property by different Temperature, doped Ni and NiO-loaded three methods, respectively.
The results indicate that the CaIn2O4 have a fine effect by sintering 700oC, MB degradation finished in 40min (TiO2 P-25 finish in 110min). The Ni doped shows wide range of wavelength up to 600 nm and possess high photocatalytic activity, when x=0.5 finished the MB degradation in 60min. furthermore, The NiO-loaded process result a lower MB degradation rate , because of CaIn2O4 decomposed as a result of Ni(NO3)．6H2O.
