Removal of methyl orange (MO) using carbon quantum dots (CQDs) derived from watermelon rinds

In this study, carbon quantum dots (CQDs) was prepared via a facile hydrothermal method. The objective for this study is to assess the performance of CQDs in photocatalytic degradation activity of methyl orange (MO) under artificial visible light source. For that reason, the prepared photocatalyst u...
