Abstract

In this work, the green synthesis of porous Fe2O3/Au nanocomposite was carried out by reacting Fe(NO3)3·with Gliricidia sepium leaf aqueous extract and chitosan template using the sol-gel method. After the gel formation, the samples were calcined at 700°C and modified with AuNP. The synthesized porous Fe2O3/Au nanocomposites were characterized using UV-Vis Spectrophotometer, Fourier Transformation Infrared Spectroscopy (FTIR), X-Ray diffraction spectroscopy (XRD), and Scanning electron microscope (SEM). Porous Fe2O3/Au nanocomposite was tested for catalytic activity for the reduction reaction model of 4-nitrophenol with NaBH4. The catalytic activities of the porous Fe2O3/Au nanocomposite in reactions were monitored by using UV-Vis spectroscopy. The XRD and FTIR confirm the compound formed is α-Fe2O3. It was found that the porous Fe2O3/Au can convert up to 79% 4-nitrophenol to 4-aminophenols.
