The present review focuses on the widely used graphitic carbon nitride (g-C3N4)-tungsten oxide (WO3) nanocomposite for photocatalytic applications. These catalysts are employed due to their easy preparation, high physicochemical...
Adsorption and activation of molecules on a surface holds the key to heterogeneous catalysis toward aerobic oxidative reactions. To achieve high catalytic activities, a catalyst surface should be rationally tailored to interact with both organic substrates and oxygen molecules. Here, a facile bottom-up approach to defective tungsten oxide hydrate (WO3 ·H2 O) nanosheets that contain both surface...
A two-step procedure was implemented to obtain tungsten oxide nanowires (WO3) doped with cobalt or silver oxide nanoparticles from metal-organic precursors, W(CO)6, Co(acac)2 and Ag(acac)2. In the first step, nanowires were grown at 400 °C using an aerosol assisted chemical vapor deposition system (AA-CVD) and subsequently annealed at 500 °C for 2 h. In the second step, metal loading (at differ...
Infrared switching electrochromic devices based on tungsten oxide" (2000). Faculty Publications from the Department of Electrical and Computer Engineering. 4. Different types of electrochromic devices for thermal emittance modulation were developed in the spectral region from mid-to far-infrared ͑2–40 m͒. In all devices polycrystalline and amorphous tungsten oxide have been used as electrochromi...
At present, sustainable water supply and energy generation are the most important challenges faced by humankind globally. Thus, it is crucial to progress ecological techniques for removal of organic pollutants from wastewater hydrogen as an alternative fossil fuels. In this study, zinc tungsten oxide (ZnWO4) nanorods, bismuth (Bi2WO6) nanoflakes, Bi2WO6/ZnWO4 (BO–ZO) nanocomposites were prepare...
Thin film of tungsten oxide (WO3) has been studied extensively as an electrochromic material and has numerous applications in electrochromic devices, smart windows, gas sensors and optical windows. In order to explore the possibility of using it in electrochromic devices, thorough study the optical properties of the WO3 is an important step. The WO3 layers have been grown by hot-filament metal ...
