Discharge of synthetic organic dye pollutants continues to result in irreversible damage to aquatic environments due to the rapid industrialization, growing urbanization and extensive use of non-sustainable resources. In particular, carbon-doped SnO₂ quantum dots (C-doped SnO₂ QDs) are interesting due to their visible-light photocatalytic activity, which is achieved through their nanoscale particle size, large surface area and efficient charge separation. In the current work, carbon doped SnO₂ q
