Un-doped and Fe-doped SnO2/Co3O4 nanocomposites were applied as photocatalyst.
The nanocomposites exhibited photocatalytic property under UV light.
The maximum degradation was observed for Fe-doped SnO2/Co3O4 (1:1) photocatalyst.
0.1 g photocatalyst is sufficient to carry out 98.3% degradation of MTZ.
