Abstract

The controlled solution spray process with superior molecular contacting between finely atomized reactants in impinging solution spray reactor was carried out with an objective to develop the nonionic surfactant (Tween-80) mediated coprecipitation protocol for the polymorph selective synthesis of lead chrome (PbCrO4) nanocrystals. Monoclinic PbCrO4nanorods with size in the range of 37.8-51.9 nm at Tween-80 loadings of 2-10 g/L were obtained. The functional group, surfactant adsorption, crystal type, size and morphology of the PbCrO4nanocrystals were determined by FTIR, XRD and FESEM analysis.
