Green Synthesis of Ag-Au Bimetallic Nanocomposites Using Waste Tea Leaves Extract for Degradation Congo Red and 4-Nitrophenol

A sustainable supply of pure water is a great challenge in most developing and third-world countries. Nanomaterial-based technology offers technological development for wastewater purification. Nanocatalysis hydrogenation nitroarene dye molecules hot model many research fields. Herein, we report eco-friendly facile to synthesize Ag-Au bimetallic nanocomposites. The synthesized nanocomposites are characterized by ultraviolet–visible spectroscopy, Fourier-transform infrared X-ray diffraction, field emission scanning electron microscopy high-resolution transmission microscopy. nanocomposite can efficiently degrade Congo red 4-nitrophenol the presence sodium borohydride. results show that it degrades entirely within 6 7 min, respectively. These could be useful green synthesis help remove organic nitroaromatics from wastewater.
