Green synthesis and synergistic catalytic effect ofAg/reduced graphene oxide nanocomposite

A nanocomposite of silver nanoparticles and reduced graphene oxide (Ag/rGO) has been developed as a catalyst for the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) with sodium borohydride, owing to the larger specific surface area and synergistic effect of rGO. A facile and rapid microwave-assisted green route has been used for the uniform deposition of Ag nanoparticles and the reduc...

Graphene Oxide/Hydroxyapatite/Silver (rGO/HAP/Ag) nanocomposite: Synthesis, characterization, catalytic and antibacterial activity

 In this paper, a novel ternary nanocomposite namely reduced graphene oxide/hydroxyapatite/silver (rGO/HAP/Ag) was prepared by a simple hydrothermal method using graphene oxide nanosheets, Ca(NO3)2, (NH4)2HPO4, and AgNO3 as starting materials. The as-prepared nanocomposite was characterized by using various photophysical techniqu...

Ultrasound Assisted Green Synthesis and Characterization of Graphene Oxide

   Graphene oxide (GO) was prepared by an improved green chemical method using graphite flakes, KMnO4, a mixture of H2SO4/H3PO4, H2O2 and HCl. In several stages, ultrasound was used to separate the oxidized layers of GO. The use of ultrasound optimizes the effect of the reacting agents, decreasing the required amou...
