From botanical waste to a biocatalyst: <i>Kigelia pinnata</i> flower-derived CQDs for triazolidine-3-thione synthesis and their <i>in silico</i> evaluation.

ABSTRACT: Biowaste-derived carbon quantum dots (CQDs) have emerged as sustainable, low-cost nanomaterials that align with the principles of green chemistry and promote waste-to-wealth conversion. In this work, CQDs were synthesized using drop-down flowers of Kigelia pinnata as a novel biowaste carbon source via a green hydrothermal method. The resulting CQDs were comprehensively characterized by HRTEM, FT-IR, UV-visible, fluorescence spectroscopy, EDS, and XRD, revealing well-dispersed spherical particles with an average diameter of 3.78 nm. They showed excellent catalytic activity as an efficient nanocatalyst for the green synthesis of 1,2,4-triazolidine-3-thione derivatives using ethanol : water (1 : 4) mixture at RT, affording excellent yields (82-97%) in short reaction times (5-20
