Question

Ammonium tungstate in octadecene for the wo3 nanoparticles synthesis

Answer 1

Tungsten oxide (WO3) is a transition metal oxide semiconductor with a widely tunable band gap,

in the range of Eg=2.5-2.8eV at room temperature. Interest was recently put on WO3 thin films

and nanoparticles [1] for a wide variety of applications in microelectronics and optoelectronics

[2], dye-sensitized solar cells [3], colloidal quantum dot LEDs [4], photocatalysis [5] and

photoelectrocatalysis [6], water splitting photocatalyst as main catalyst [7-13] and methanol

oxidation catalyst [14]. Environmental applications may also benefit with the use of WO3 as a

visible light photocatalyst to generate OH radicals in the wastewater treatment [15], bacteria

destruction [16] and photocatalytic reduction of CO2 into hydrocarbon fuels [17]. Yin et al. [18]

have reported high hydrophobic properties and improved performances of WO3 as anode

materials in lithium ion batteries (LIB). WO3 has also been used in so-called smart windows

[19] for energy-efficient buildings, flat-panel displays, optical memory and writing-readingerasing

devices. Moreover, WO3 shows excellent functional activity to various gases, such as H2

[20], H2S, NOx, trimethylamine, and other organic compound gases such as acetone sensing in

exhaled breath [21]
