A comparative study on the effect of palladium dopant concentration on the photocatalytic properties of tin(IV) oxide / Amzamir Noor Kamarul Bahrin Noor and Dr. Vicinisvarri Inderan

Several type of semiconductor photocatalysts such as TiO2, ZnO and SnO2 have been applied in treating dye containing wastewater. However, the application of SnO2 metal oxides as photocatalysts still remain limited despite the potential of the material to oxidize and degrade pollutant materials in wa...
