Influence of sodium dodecyl sulfate on the fabrication of zinc oxide nanoparticles

Influence of sodium dodecyl sulfate on the fabrication of zinc oxide nanoparticles Dispersive ZnO nanoparticles with a primary particle size of about 70 nm and an average agglomerate size of about 2.0 μm were synthesized via the precipitation-thermal decomposition route using ZnSO4 and Na2CO3 as the reactants and sodium dodecyl sulfate (SDS) as the surface modification agent. The presence of minor amounts of SDS in the formation of hydrozicite (Zn5(CO3)2(OH)6) precursor changed the agglomeration size of ZnO from 9.7 to 2.0 μm and the primary particle size of ZnO from about 45 to 70 nm. Molecular simulation based on the DISCOVER model and COMPASS force field indicated that SDS was adsorbed on the surface of Zn5(CO3)2(OH)6 mainly via the coulomb and hydrogen bond interactions. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals

Abstract

Dispersive ZnO nanoparticles with a primary particle size of about 70 nm and an average agglomerate size of about 2.0 μm were synthesized via the precipitation-thermal decomposition route using ZnSO4 and Na2CO3 as the reactants and sodium dodecyl sulfate (SDS) as the surface modification agent. The presence of minor amounts of SDS in the formation of hydrozicite (Zn5(CO3)2(OH)6) precursor changed the agglomeration size of ZnO from 9.7 to 2.0 μm and the primary particle size of ZnO from about 45 to 70 nm. Molecular simulation based on the DISCOVER model and COMPASS force field indicated that SDS was adsorbed on the surface of Zn5(CO3)2(OH)6 mainly via the coulomb and hydrogen bond interactions.
