Size Adjustment of Iron Phosphate Nanoparticles by Using Mixed
Acids
|
|
ABSTRACT: In this work, the size adjustment of FePO4 nanoparticles in the range of 9?50 nm was conducted on a general platform of coupling fast precipitation in a microreactor and thermal treatment process. Specifically, we used the mixture of nitric acid and phosphoric acid as the continuous fluid to change the free Fe3+ concentration and control the supersaturation of FePO4 in fast precipitation. Inductively coupled plasma optical emission spectroscopy (ICP-OES) and X-ray diffraction (XRD) verified that as-prepared nanoparticles were high-purity amorphous FePO4·2H2O. Transmission electron microscopy (TEM) verified their good dispersity and narrow size-distribution (standard deviation, ～5 nm). Brunauer?Emmet?Teller (BET) and Cr (III) adsorption verified their property accordant as ion adsorbents. The effect of mixed acids on species with respect to iron was also investigated by UV?vis spectra. The technique would be easily scaled up for size controllable and property accordant FePO4 nanoparticles preparation. 发自小木虫Android客户端 |
