Green Synthesis, Photocatalytic And Photoelectrochemical Performance Of Au-Graphene Nanocomposite, Mohammad Mansoob Khan Dr, Mohammad Ehtisham Khan, M. H. Cho
Dr. Mohammad Mansoob Khan
A simplistic and environment friendly approach using electrochemically active biofilms (EABs) was developed for the synthesis of Au-Graphene (Au-G) nanocomposite without the use of surfactants or capping agents. The as-prepared Au-G nanocomposite was characterized by X-ray diffraction, diffuse reflectance spectroscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, photoluminescence spectroscopy, and transmission electron microscopy. In this study, the anchoring of gold nanoparticles (AuNPs) on graphene sheets was achieved using an EAB. The EAB assists in the bio-reduction of Au3+ to Au0, and the AuNPs prevent the aggregation of graphene sheets and keep them apart because of the decrease in attractive forces between the …
