ABSTRACT = {In this study Fe doped SnO<sub>2</sub>-SnS<sub>2</sub> (FS) and Fe doped SnO<sub>2</sub>-SnS<sub>2</sub>-polypyrrole (FS-PPY) 
were synthesized and studied for the methylene blue (MB) egrdation under UV light. The 
morphological and structural characterizations were carried out by FTIR, SEM-EDX, 
XRD and XPS. It has been found that FS-PPy degrade methylene blue upto 98 % under 
optimized conditions as pH =3, dye concentration = 10 ppm, oxidant dose = 2 mM. The 
Langmuir-Hinshelwood kinetics model fitted well. The optimization was studied using 
response surface methodology. Scavengers study was carried out to find the active species. 
Reusability of photocatalyst was evaluated up to 5 cycles. },
