![عکس صفحه اول مقاله: Novel synthesis of Ag@Co/RGO nanocomposite and its high catalytic activity towards hydrogenation of 4-nitrophenol to 4-aminophenol Novel synthesis of Ag@Co/RGO nanocomposite and its high catalytic activity towards hydrogenation of 4-nitrophenol to 4-aminophenol](/preview/png/1271612.png)
• A novel method was developed to synthesize the Ag@Co/RGO nanocomposite.
• Remarkable high catalytic activity of Ag@Co/RGO nanocomposite was observed for 4-nitrophenol reduction.
• The catalytic activity was noticeably higher than Ag/RGO and Co/RGO.
We report a facile and green method for the synthesis of Ag@Co/RGO nanocomposite using two reducing agents, l-ascorbic acid (L-AA) and sodium borohydride (NaBH4) at room temperature (RT) and explored the practical application for catalysis reaction. The structure, composition and morphology of the catalyst were characterized by using X-ray diffraction (XRD), vibrating sample magnetometer (VSM), Fourier transform infrared spectroscopy (FTIR), Raman, scanning electron microscopy (SEM), Transmission Electron Microscopy (TEM), X-ray Photoelectron Spectroscopy (XPS) and energy dispersive X-ray spectroscopy (EDX) techniques. Further, the catalytic activity of Ag@Co/RGO nanocomposites was investigated for hydrogenation of p-nitrophenol (4-NP) to p-aminophenol (4-AP) and it showed a remarkable high activity 45 s at RT with excellent stability up to 5 cycles.
