Synthesis and photocatalytic properties of Zn²⁺ doped In(OH)₃ obtained by the microwave-assisted hydrothermal method

Full text: The indium hydroxide semiconductor with a wide band gap (Eg) estimated to be 5.15 eV is attractive due to its electronic and optical properties [1-2]. Crystalline zinc-doped indium hydroxide structures were prepared by the rapid and efficient microwave-assisted hydrothermal (MAH) method. X-ray diffraction (XRD) and UV-visible (UV-vis) spectroscopy were used to characterization the materials. The XRD shows patterns of pure In(OH)₃ nanostructures and with 4% of Zn²⁺ . XRD was used to verify the composition and phase evolution of the samples. All diffraction peaks in XRD patterns could be indexed to the cubic lattice related to the In(OH)₃ phase (PDF card No . 16-161). References: [1] S. Avivi, Y. Mastai, A.
