Morphology-Controllable Synthesis and Characterization of ZnMoO4 Nanoparticles

摘要

In this work,nano-sized zinc molybdate (ZnMoO4) with several morphologies were prepared through introducing different template agents into hydrothermal system,in which ZnCl2 and Na2MoO4 were used as raw materials.Their structures and morphologies were characterized by XRD,FTIR and SEM techniques.Results show that after constant temperature of 150°C for 4h,ZnMoO4 nanoparticles (～ 200 nm) were obtained in water medium.While in citric acid,CTAB and EDTA reaction templates,corresponding products are needle-like (400 nm × 4 μm),plate-like(350 nm × 1.5μm × 2 μm) and micro flower-like assembled by nanorods (300 nm × 600 nm),respectively.All of them were monoclinic wolframite-type structure,and their photoluminescent (PL) spectra are also observed.
