摘要

The development of environmentally friendly catalysts is a key goal in green chemistry. In this study, we report the green synthesis of reduced graphene oxide (rGO) using aqueous Datura stramonium leaf extract as a biogenic reducing agent. The resulting material, referred to as DARGO D, was characterized using UV–vis spectroscopy, FTIR, XRD, Raman spectroscopy, SEM–EDX, and TEM–SAED to confirm effective deoxygenation and partial restoration of the graphene π-network. DARGO D was then explored as a sustainable, metal-free catalyst for the regioselective reduction of styrene oxide (SO) and its substituted derivatives to their corresponding alcohols in water using sodium borohydride (NaBH₄) as a mild reductant. Under optimized conditions, a high yield (94%) of 2-phenylethanol (2-PEol) was achieved with excellent selectivity. DARGO D also demonstrated good recyclability across multiple reaction cycles without significant loss of activity. This dual-purpose investigation emphasizes the intriguing possibilities of Datura-based rGO as both a green nanomaterial and an effective catalyst for eco-benign epoxide transformations.
