Abstract

Organic ligands are widely used in the synthesis of metallic complexes, which can be burned and eliminated from the coordination sphere at high temperatures and remaining only oxide group. The reaction of Ethylenediaminetetraacetic acid (EDTA) as an organic ligand and antimony trichloride in a domestic microwave leads to formation of antimony-EDTA complex. Then, the resulting compound was calcined and got nano antimony oxide. The product was characterized by powder x-ray diffraction (XRD), fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FE-SEM) and UV–vis diffuse reflectance spectrum (DRS). This technique is a simple, fast, environmental friendly and can draw a usable viewpoint for the synthesis of nanomaterials.

Summary

Introduction

Oxide nanoparticles have attracted great attention over past decade due to novel properties compared with bulk materials [1,2,3]. There are many reports on the synthesis, structure, and applications of nanocrystalline materials [4,5,6,7]. Antimony oxides are well known to exist in several different phases including Sb2O3, Sb2O4, Sb6O13, Sb2O5 and the polymorphism, which have attracted great attention in the field of catalysts, medicines, optics and semiconductors. Among the different antimony oxides, Sb2O4 is the most common form of polymorphism, which has two types, namely the orthorhombic α phase and monoclinic β phase, respectively [8]. For the first time, we report the synthesis of leaf-like α-Sb2O4 nanostructures by the microwave assisted method, which is a simple, fast, environmental friendly and green technique
