Abstract
Environmental concerns arising from industrial activities and population growth have encouraged the development of green chemistry, a sustainable approach to synthesis. Researchers have explored various techniques for the eco-friendly synthesis of Schiff bases, including microwave irradiation, ultrasound irradiation, grinding, and natural acids. These versatile compounds, known for their unique chemical properties, have found diverse applications in various fields. Recently, the use of Schiff bases as dyes in dye-sensitized solar cells (DSSCs) has drawn the attention of researchers. DSSCs have advantages over silicon-based solar cells, such as a low cost of fabrication and the ability to operate under low light conditions. Schiff bases can be used as adsorbents to remove toxic metals from water. By embracing sustainable synthetic methods, researchers have reduced the environmental impact associated with Schiff base production and employed these compounds to promote environmental sustainability. This review describes the green synthesis of Schiff bases and their potential applications for environmental protection.
