Abstrakt: A novel low temperature hydrothermal synthesis of II-III2-VI4 (II = Zn, Cd; III = In; VI = S) mixed ternary chalcogenide semiconductors as visible photocatalysts for solar hydrogen production was performed. In this work, an X-ray diffraction based structural and microstructural study of chalcogenide semiconductors type CdxZn1-xIn2S4 (0 ≤ x ≤ 1) is reported. The investigated powder samples were synthesized by a hydrothermal technique, using a Teflon lined closed autoclave with self-generated pressure, at 180°C for 20 hours. Rietveld method based on pseudo-Voigt profile fitting function was applied to perform a simultaneous refinement of X-ray diffraction patterns concerning both material structure and microstructure. The Rietveld refinement of the X-ray diffraction data has been done using the MATCH, MAUD and PowderCel softwares. [ABSTRACT FROM AUTHOR]
