Sol-gel synthesis of SnO2-MgO nanoparticles and their photocatalytic activity towards methylene blue degradation

- A simple sol-gel method for the synthesis of SnO2-MgO nanoparticles is reported.
- Band gap of SnO2 can be tuned by varying the magnesium content in SnO2-MgO.
- SnO2-MgO shows good photocatalytic activity towards degradation of methylene blue.
