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

Purity:~99%

Appearance:Dark blue powder

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.

Great water cup
Size: 40 Ounces, Color: Peony, Size: 40 Ounces, Color: Peony
Love this water cup! I like to use it around the house. I like how much water it holds, because I drink a lot of water. The color selection of these cups is really good too; I went with the peony cup. It is very vibrant and bold in color. I would say as for on the go, they can get pretty heavy if walking with it full of water, so maybe not the best choice if you are travelling by foot and carrying it. One thing I will say is that this keeps the water VERY cold for a long period of time! Definitely good in that aspect. The handle is very pleasant to hold too, as it has a soft silicon-like material along the handle, and feels very sturdy and thick. I do wish that the straw was more clear, but that isnt too hard to replace. If you want a water cup for around the house, I would reccommend

Great purchase
Size: 40 Ounces, Color: Rose Quartz 2.0
I was a Stanley skeptic. I couldn’t understand what the big deal was or why the internet was freaking out. I saw the video of the Stanley cup surviving the car fire (and I think the ice was still inside). So I tried it. I drink SO much more water now! I love decorating my Stanley with all the fun accessories and it holds a nice amount of water. It feels durable and good quality. I’ve had my Stanley for a year now and I’m even considering getting another so I can have one while the other is being washed. They are easy to clean as well because of the metal inside. There are two issues I’ve had since I got the Stanley cup. Once it was dropped, and the lid broke. Easy to buy more so not the biggest issue. The cup survived the fall just fine, not a mark on it. The other issue I keep having is my lid gets stuck and becomes hard for me to open sometimes. I have a bad thumb and wrist so often I have to have my spouse open it for me. It keeps my water cold all day. If I put ice in before I go to sleep it’s still cold in the morning. I love these cups and would recommend them to anyone looking to drink more water. If you like your water bottle you will drink more water and want to bring it with you.

Very strong and cute tumbler
Size: 40 Ounces, Color: Rose Quartz 2.0, Size: 40 Ounces, Color: Rose Quartz 2.0
Great quencher to get. I got this for my self and I love it so much. It's super cute and the color I got is a light soft pink. The size is big which is great since I like having enough coffee to last me all day. It keeps my drinks cold and warm or what ever temperature it is for a good amount of time which is great for anyone who is out for long periods of time. The quality overall is very good. The handle is big, comfortable and easy to grip and the quencher fits perfectly on my gym bag. Only downside is that it did get a smudge on it after I removed the paper that it had on the bottom. I tried removing the smudge it feels sticky like glue but it didnt get removed so I had to put a sticker over it to cover it up.

This is a great basic protective shower curtain
Color: 1a Peva Clear Premium, Size: 72"W x 72"L (Pack of 1)
This is a great product. It allows me to have a decorative curtain that won’t get water damaged or mildewed. The price point was right on and I will definitely be buying it again. Pros: The thickness is great. Not too flimsy. I was also impressed with the fact that there wasn’t a chemical smell like we often get with plastic curtains. It was very easy to put up and was just the right length to keep the water in the shower while it does a great job protecting the decorative curtain. It also has weights to assist it with hanging correctly. Cons: Make sure to spread it out after your shower to prevent water stains .
