Pb(OH)I-graphene composite: Synthesis and characterization

Pb(OH)I-graphene nanocomposite, has been successfully prepared via combination sonochemical and hydrothermal methods. Lead nitrate, lithium iodide and N,N-bis(salicylidene)-ethylenediamine (H(2)salen) were applied as starting reagents to fabricate Pb(OH)I-graphene nanocomposite. For preparing nanoparticles (NPs)-graphene composite post-graphenization method was applied. In synthesis NPs-graphene with post-graphenization method, graphite oxide as starting reagent was synthesized via Hummer method. The effect of ultrasonic irradiation and H(2)salen were investigated on the particle size of nanoparticles and their distribution on the graphene sheets. H(2)salen and sonication treatment were confirmed to be the crucial factors that determining the formation of one-dimensional Pb(OH)I micro/nanostructures on the surface of graphene nanosheets. The as-produced nanocmposites were characterized with the aid of XRD, SEM, TEM, EDS and FT-IR. (C) 2014 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.
