Effect of Surfactant Types on the Size of Tin Oxide Nanoparticles

“…At the same time, the unique morphology and structure of semiconductor oxides can offer a lot of promising applications. Among them, as n-type of semiconductor, tin oxide has attracted great interest due to its properties such as wideband-gap (E g = 3.6 eV, at 300 K), unique optical and electrical properties [2,3]. SnO 2 has great significance in widely technological applications such as dye-based solar cells, electrochromic devices [4], photovoltaics [3], transparent electrodes, catalysts, gas sensing, lithiumion batteries [2] and transistors [5].…”

There are several research methods to synthesize SnO 2 nanostructures with high purity level, well dispersibility and controllable sizes, such as spray pyrolysis, hydrothermal process, evaporating tin grains in air, chemical vapor deposition, thermal evaporation of oxide powders, rapid oxidation of elemental tin and the sol-gel method, and hydrothermal method.…”

Rational design of SnO2 aggregation nanostructure with uniform pores and its supercapacitor application

“…In particular, tailoring the size and shape of tin oxide (SnO 2 ) crystal has attracted great attention for its wide application in catalysts [8,9], gas sensors [10][11][12][13][14], solar cells [15,16], and lithium ion batteries [17][18][19]. Over the past two decades, different morphologies of SnO 2 nanostructures have been synthesized, such as 0D nanoparticles [1,7]; 1D nanowires [20], nanorods [21], nanotubes [22], and nanobelts [6]; and 2D nanosheets [2].…”
