Product Overview

WO2.9, also known as blue tungsten oxide or blue tungsten, is a compound containing a mixed valence state of tungsten (VI) and tungsten (V). The chemical formula of WO2.9 indicates that the atomic ratio of tungsten (W) to oxygen (O) is about 2:9, but in fact it represents a mixed oxide containing different valent states of tungsten. This compound is formed by the combination of tungsten with oxygen in two valence states, W+6 and W+5, so its chemical formula can also be considered as an average composition used to describe its overall chemical properties. With its high chemical activity, WO2.9 can participate in various chemical reactions. Its reduction and oxidation properties are relatively weak, but the specific performance depends on the reaction conditions and the nature of the reactants. Moreover, WO2.9 also has good photochromic and electrochromic effects, and its color may change with different factors such as particle size or illumination.

Technical Parameter

Size:0-300nm

Product Features

Catalytic activity and selectivity: WO2.9 has excellent catalytic activity and selectivity, and is suitable for various catalytic reactions such as hydrogenation, dehydrogenation, oxidation and reduction. In the fields of petrochemical industry, fine chemicals and environmental protection, WO2.9 as a catalyst can significantly improve the reaction efficiency and product quality stability: the stability of nanometer vanadium dioxide is relatively high, thanks to the special structure of its surface ion ripples, so that it can maintain good performance in a variety of environments.

Optical properties: WO2.9 has a unique blue luster, which can be used as an additive to materials such as optical glass, optical thin films and optical coatings to improve the optical properties and stability of these materials. It can also be used to prepare transparent heat insulation coatings and solar photosensitive films to meet the needs of optical materials in different fields.

Application Fields

Catalytic reaction: WO2.9 has excellent catalytic activity and selectivity, and can be used as a catalyst for hydrogenation, dehydrogenation, oxidation and reduction reactions to improve the reaction efficiency and product quality.

Lithium ion battery: WO2.9 can be used as a cathode material for lithium ion battery to improve the capacity and cycle performance of the battery.

Solar cells: WO2.9 can also be used as a photoelectric conversion material for solar cells to improve the conversion efficiency and stability of solar cells.

Optical field: WO2.9 has a unique blue luster and optical performance, which can be used as an additive for optical glass, optical film and optical coating materials to improve the optical performance and stability of materials.

Coating material: WO2.9 can be used as an additive for anticorrosion coating and wear resistance coating to improve the corrosion resistance and wear resistance of the coating.

Excellent, highly absorbent, napkins for every meal
Size: 400 Count
These napkins are amazing! They are soft and plushy feeling. The absorption is incredible and they have a nice , comfortable texture for wiping your hands and face when eating. I believe these can also be used as a paper towel when needed because the absorbency is so great. I am very sensitive to scents which I pick up on more than the average person and these napkins do not have a weird smell to them . I think these are great napkins for all to enjoy. The price is very reasonable for the amount I received (400ct) 🤗❤️

Great napkins
Size: 200 Count (Pack of 1)
I keep ordering these BOUNTY PAPER NAPKINS because their versatility, durability foldability appearance and size; these are all great attributes of these napkins. I don't use them for bathroom use but on occasion I do put water on a couple of them to cool my face off which is awesome because they don't tear with that much water as I put on them. The only thing I would suggest for BOUNTY to change is the roughness and thickness of the napkins. They're a little rough not so rough to where I can't stand them but if they were just a little bit softer, not much just a tad bit. Maybe also a little bit thicker. Besides that they're awesome and worth the money
