Abstract

Bisphenol A (BPA), a major industrial effluent and suspected endocrine disrupter in animals. The increased release of pollutants into natural ecosystems results in adverse impacts on associated life. Several traditional methods, such as adsorption, biochemical, coagulation, and electrochemical, successfully degrade the BPA, but these methods cause secondary pollution by generating toxic by-products. Since the last few years, plant-derived carbon dots (CDs) and carbon quantum dots (CQDs) are gaining the attention of researchers in the fields of biomedical and environmental sustainability. CDs are emerged as efficient photocatalysts in degrading the toxic dyes and environmental effluents. In the present study, A sand bath assisted synthesis of CDs and nitrogen doped CDs (N-CDs) was achieved using leaves of Nyctanthes arbor-tristis leaves. The high band gap energy attributed with enhanced electron excitations and there is no observed difference in functional groups of both samples. In HRTEM analysis both sample shown irregular shapes and clustered agglomeration with particle size diameter less than 6 nm. In vitro antioxidant property revealed CDs with lowest inhibitory concentration 50 (IC₅₀) of 24.44 µg mL⁻¹. In terms of BPA degradation, both samples were shown approximately similar degradation (%) but differ in their rate constants of pseudo-first order kinetics. These plant derived CQDs are green, rapid, reusable, low cost and found as efficient photocatalysts which can be as alternative photocatalysts to conventional materials.
