Name:Vanadium dioxide nanoparticles(VO2)

Product Overview

 

Vanadium dioxide is a deep blue crystal powder with a monoclinic crystal structure, which can be industrially produced by gas reduction of ammonium vanadate or vanadium pentoxide (V2O5). VO2 is a amphoteric compound that is slightly soluble in water and equally soluble in acidic or alkaline solutions; When dissolved in acidic solution, it generates divalent vanadium oxide ions (VO2+), which appear light blue; When dissolved in alkaline solution, it generates vanadate salts M2V4O9 or M2V2O5. VO2 is in a metastable state, where V4+is easily oxidized to V5+, exhibiting relatively weak antioxidant capacity. VO2 is a polycrystalline metal oxide with five main structures: VO2 (M), VO2 (R), VO2 (A), VO2 (B), and VO2 (C).

Product Features

 

Phase transition characteristics: Vanadium dioxide nanoparticles can achieve a reversible transition from insulating phase to metallic phase at a specific temperature (68 ¡ãC, accompanied by significant changes in conductivity and optical properties.

High specific surface area: Nanoscale vanadium dioxide particles have a larger specific surface area, which is beneficial for increasing their surface active sites and catalytic efficiency.

Strong chemical inertness: The surface of nano vanadium dioxide has a large number of active sites, but due to the small amount of surface vacancies, its chemical inertness is very strong, and its adsorption performance for various harmful gases is excellent.

Good stability: Nano vanadium dioxide has relatively high stability, thanks to its special structure of surface ion ripples, which enables it to maintain good performance in various environments.

High catalytic activity: Nanoscale vanadium dioxide particles have significantly improved catalytic activity due to their high specific surface area, making them suitable for various catalytic reactions.


Application Fields

 

Smart windows: By utilizing the phase transition properties of vanadium dioxide nanoparticles, smart windows can be prepared. At high temperatures, windows appear metallic, blocking heat transfer; At low temperatures, windows become transparent, allowing light to pass through. This smart window can automatically adjust its transparency according to changes in ambient temperature, improving energy efficiency.

Photoelectric switch: Based on the phase transition characteristics of vanadium dioxide nanoparticles, high-speed photoelectric switches can be prepared. By controlling the temperature, switching between different phase states can be achieved, thereby regulating the transmission of photoelectric signals. This type of photoelectric switch has important applications in fields such as information processing and data storage.

Sensors: Various sensors can be prepared by utilizing the significant changes in electrical and optical properties of vanadium dioxide nanoparticles during phase transition. For example, using changes in conductivity to sense physical parameters such as temperature, humidity, and pressure; Utilizing changes in optical properties for optical sensing and spectral analysis.

Catalyst: Nano vanadium dioxide is widely used as a catalyst for various catalytic reactions due to its high catalytic activity and strong chemical inertness. For example, it can be seen in reactions such as nitration, ethane dehydrogenation, methane oxidation, and hydrogenation of formic acid.

Comfortable and Supportive, but Adjust the Filling
Color: White-cooling Basic, Size: Queen(Pack of 2), Color: White-cooling Basic, Size: Queen(Pack of 2)
I’m very happy with this pillow. The size is big and it feels soft while still providing good support, perfect for midnight scrolling on TikTok. One thing to keep in mind is that it can feel a little too tall if you use all of the filling that comes with it. The good news is that you can easily adjust the amount of filling to find the height that works best for your sleeping position. Once I customized it, it was much more comfortable. Overall, great quality, comfortable, and worth the purchase.

BEST PILLOWS EVER!!!
Color: White-cooling Basic, Size: Queen(Pack of 2)
I am very picky with my pillows because I have a bad neck and I can never seem to find a good pillow. But I tried this pillow because it had everything I was looking for and the price was great! You get two of them and they are absolutely awesome.! normally I would need to lay on two pillows to try and get comfortable but with these pillows I just lay on one and I wake up with no neck pain. They really have a nice cooling effect. They actually puff up immediately after opening them. All you have to do is just shake them up and the pillow just puffs straight up.. It comes with extra cushioning if you want it to make it firmer and if you don’t want it as firm as it is, you can actually take some out. It really is such a beautiful pillow. It’s perfect in every way to me being such a picky pillow person. You just lay your head down on it and it forms around your neck and your head and when you get up, it goes right back to its normal form. It doesn’t get flat and I love it. I completely recommend this to anyone who is a person who has a hard time finding a really good pillow.

Top of the line, best pillows Ive ever had
Color: White-cooling Basic, Size: Queen(Pack of 2)
These pillows are top of the line! I bought them in 2024 and they are still fluffy. When they lose a little fluff, you just punch em around a little bit and voila, like new again. They have kept their shape cery well and do great for cooling. I haven't had to add more filling yet either. I just laid my head on one and thought, I need to do a review cause everytime i lay on these pillows its like clouds. My head is heavy and this is relief :-D

Weird smell
Color: White-cooling Basic, Size: Queen(Pack of 2)
The pillows are great for someone looking for something cool and comfortable. We loved them so much that we bought a second pair. However, we were seriously disappointed with the odor of our last purchase. They give off a strong and indescribable chemical/burning plastic smell so nauseating that it’s difficult to sleep with. We’re hoping this issue will resolve with a couple more washes of the pillow cases, but am worried the source is the stuffing itself.
