Implication
Experimental study demonstrates enhanced photocatalytic degradation of azo dye in water using coupled SnO2/TiO2 thin films, highlighting improved solar purification efficiency.
Key Points
- Investigate the photocatalytic degradation efficiency of an azo dye using coupled tin dioxide and titanium dioxide (SnO2/TiO2) semiconductor thin films.
- Fabricated coupled SnO2/TiO2 semiconductor thin-film catalysts.
- Subjected an aqueous model azo dye solution to photocatalytic degradation under light illumination using the coupled films.
- Coupled SnO2/TiO2 thin films achieved significantly enhanced photocatalytic degradation rates of the azo dye compared to single-component semiconductor films.
