Surfactant CTAB-assisted synthesis and gas-sensing characteristics of SnO2 nanomaterials Heyun Zhao1, a, *, Qiuping Jiang1, b, Yuehuan Li1, 2, c 1Department of Materials Science and Engineering, Yunnan University, Kunming 650091, China 2School of Pharmacy and Chemistry, Dali University, Dali 671200, China ahyzhao@ynu.edu.cn, bqiuping26@yahoo.cn, cloneman2@163.com Keywords: Tin oxide; Rutile structure; Surfactant CTAB; Gas sensor Abstract.
The indirect heating structure was selected to fabricate sensors and looked into the gas sensing characteristics.
It reveals that pure SnO2 with tetragonal rutile structure was obtained.
Fig. 1(d) shows a high resolution transmission electron micrograph (HRTEM) of SnO2 nanoparticles, which displays structure uniform and clear lattice fringe.
The single-phased, pure rutile structure SnO2 nanomaterials can be obtained by thermal treatment at 500 oC after microwave radiation.

Thirdly, the stability of the core can be enhanced by forming core/shell structures[3].
Lastly, even doping can be achieved by depositing a layer of shell on the core structures[4].
Surface structure reconstruction occurs at this stage.

Phase structure of Bi2Fe4O9unchanged with the increase of [OH-] and maintained orthorhombic structure.
At present, Bi2Fe4O9fine powder was synthesized by wet chemistry methods, such as coprecipitation method and sol-gel method.
The results suggest that monocrystal Bi2Fe4O9 nanoparticles possess the same crystalline structure as that of [OH-]=1mol/L.
As can be seen, both the tiny nanoparticles and the matrix are monocrystal structure, and all patterns are uniform, implying they are homogeneous.
