Abstract

This research studies the fabrication of graphene /gold nanoparticles (AuNPs) hybrid materials by a facile method. To incorporate AuNPs on to graphene, graphene colloidal solution and gold chloride tetrahydrate with various concentration of 1, 4, 8, 40 and 80 weight percent were mixed and stirred overnight at ambient temperature for 24 hours and further reduced with Sodium borohydride. To study the catalytic activity of graphene / AuNPs hybrid materials, the obtained products were subjected to test for the formaldehyde degradation using UV-visible spectroscopy. The study illustrates that graphene / AuNPs hybrid material (8 wt% AuNPs) at pH 10 shows catalytic activities for formaldehyde degradation around 36 percent while the catalytic activities of graphene / AuNPs hybrid materials with 40 and 80 wt% of AuNPs reach more than 80 percent. The obtained products of graphene / AuNPs hybrid materials could be applied as catalyst for the degradation of Formaldehyde in solutions / fluids.
