| description | The rice granular CaIn<sub>2</sub>O<sub>4</sub>/In<sub>2</sub>O<sub>3</sub>was successfully synthesized <i>via</i> the electrospinning method using calcium nitrate and indium nitrate as the raw materials, polyvinylpyrrolidone (PVP-K30) as a template and ethanol as a solvent. The samples were characterized by X-ray diffraction (XRD),scanning electron microscope (SEM),energy spectrum analysis (EDS),transmission electron microscopy (TEM),UV-vis diffuse reflectance spectroscopy (UV-vis DRS) and N<sub>2</sub> adsorption-desorption isotherm. The effect of pH value and the initial concentration of methylene blue(MB) on the photocatalytic performance of CaIn<sub>2</sub>O<sub>4</sub>/In<sub>2</sub>O<sub>3</sub> was discussed. The results show that the composites consist of orthorhombic CaIn<sub>2</sub>O<sub>4</sub> and cubic In<sub>2</sub>O<sub>3</sub>, with particle size of (650±140) nm, energy gap of 3.48 eV and specific surface area of 17.2 m<sup>2</sup>·g<sup>-1</sup>. The degradation rate of MB reaches 92% when it is irradiated by simulated sunlight for 120 min and the photocatalysis degradation process fits the first-order kinetic model. Meanwhile, CaIn<sub>2</sub>O<sub>4</sub>/In<sub>2</sub>O<sub>3</sub> has an excellent reusability and stability. The coupling of CaIn<sub>2</sub>O<sub>4</sub> and In<sub>2</sub>O<sub>3</sub> enables the photogenerated carriers to be effectively separated and therefore produces CaIn<sub>2</sub>O<sub>4</sub>/In<sub>2</sub>O<sub>3</sub> composites with excellent photocatalytic performance. |
