Hydroxyapatite/PCL/Fe3O4 waste-based composite: An efficient green catalyst for spirooxindole-chromene synthesis under ultrasonic irradiation

Case Studies in Chemical and Environmental Engineering
Hydroxyapatite (HAp) derived from bioresources has garnered attention due to its advantageous catalytic capabilities. In this study, HAp was synthesized from green mussel shell waste and subsequently composited with Fe3O4 for utilization as a catalyst in
