Product Overview 

Single-atom catalysts are a class of catalysts in which isolated single atoms are uniformly dispersed on the carrier and without any form of interaction between each individual atom. The active metals in single-atom catalysts are uniformly dispersed on the carrier in the form of single atoms, forming a unique coordination environment with the surrounding atoms. Common single-atom species of single-atom catalysts are precious metals such as Pt, Pd, Au, Ir, Ag and Rh and non-precious metals such as Fe, Co, Ni and Cu. Commonly used carriers are metals and metal oxides, such as Fe2O3, TiO2 and Al2O3, as well as carbon-based carriers, such as carbon nanospheres, nanocarbon fibers, graphene, metal-organic frame-derived carbon, covalent triazine frame, carbon nitride and phthalocyanine-derived carbon. The preparation methods include high-temperature pyrolysis method, impregnation method, atomic layer deposition method, metal-organic frame derivative method and electrochemical deposition method. The single atom catalyst provided by XFNANO uses the pyrolysis of nitrogen-containing carbon organic matter (such as PVP) at high temperature to obtain the amorphous nitrogen-doped carbon carrier, and the metal atoms take nitrate or chloride as the precursor.

Product Features

 

High activity: Due to the high dispersion of metal atoms on the carrier, each metal atom can become an active centre, thus increasing the activity of the catalyst. 

High selectivity: the regulation of reaction selectivity can be achieved by controlling the coordination environment of the metal atoms and the nature of the carrier. 

High stability: the strong interaction between the metal atoms and the carrier can improve the stability of the catalyst. 


Application Fields

Energy: Single-atom catalysts can be used to improve the efficiency of the oxygen reduction reaction in fuel cells, thereby enhancing the performance of the cells. It can also be used in electrolysis of water to produce hydrogen to effectively promote hydrogen precipitation reaction, reduce the reaction overpotential, and improve the efficiency of hydrogen production. 

Environmental protection: monatomic catalysts can be used to degrade organic pollutants. In wastewater treatment, iron monatomic catalysts can be used to catalyse the degradation of organic pollutants such as phenols and dyes.

 

Chemical production: monatomic catalysts help to achieve the hydroconversion of nitrogen under mild conditions and improve the reaction rate and selectivity of ammonia synthesis. 

Petrochemicals: monatomic catalysts can effectively remove sulphur compounds from petroleum products and reduce the sulphur content of oil. 

Fine Chemicals: Metal monatomic catalysts can catalyse specific organic reactions for the synthesis of drug molecules, improving reaction selectivity and yield.

Exactly what I wanted!
It is really exactly what I was looking for. I've been living with my jewelry in ziplock bags since we moved over here and everything fits perfect. I saw some reviews that claimed it was unstable but I tested it and it seems sturdy though I'm not hanging heavy pieces. It is a nice size and I love the little ring basket. It also feels pretty decent quality too. Glad I got the black one as I'm not sure where I have it that the copper/bronze would look right. I think it is elegant, practical and I wish I could post a photo with my pieces on it to show that it really holds things beautifully.

Looks great by my bed!
Even my boyfriend keeps commenting how much he likes it. It's a usable piece of art! I will comment that the earring holes can be a little tricky since the leaves are turned all different ways. You have to be strategic with how you line up your long/dangle-y earrings with your studs so everybody fits and can be seen. A little tricky. But not a deal breaker - especially when it's so easy on the eye. The other slight negative is that this really isn't the best necklace holder. I would have thought, "No problem!" But it's a bit awkward. Especially if you actually intend to see all your earrings. You'll end up hanging most of your necklaces from the top most branch - but they slide down into the crevice to stay. Then you've got a lot of overlapping. And trickiness to retrieve the exact necklace you want with ease. However, this is still a fabulous earring tree. I can't say enough good things about it. Love the little basket for miscellaneous. Hair bands, lip gloss, etc.

Beautiful jewelry display
Color: Bronze-Tone
A few rough edges, but all in all well made and attractive. Holds lots of earrings and I can drape my necklaces on the tree. There's a nice bowl for bracelets and a nice tray that forms the base.

Gorgeous
Color: Bronze-Tone
It really is pretty to look at. To be honest arranging the earring on the tree is a bit of a pain, because the leaves tilt in different directions, and you have to play with it a bit to get the earrings to hang the way you would like them, but once you figure it out, they look very nice. I just adore it because it looks so pretty. I use the basket on the side for rings and watches, and the little plate in the base for a few miscellaneous pieces like necklaces or bracelets for balance and because they look nice. You'll love it.

gorgeous, and worth the purchase.
Color: Bronze
I wasn't sure about purchasing the jewelry stand at first (I had my doubts), but those doubts quickly disappeared upon the arrival/unpackaging of the jewelry stand. SHIPPING/PACKAGING It was nicely packaged, and not bent or damaged when I recieved it. The stand was a little wobbly (due to careless measuring of the copper balls, the fault of the manufacturer) THE PRODUCT The pictures are not how it is. Remember that. I thought the tree would be more three dimensional, you know- like a real tree. It wasn't, though. It was like someone took a 2D copper tree and made it stand up. It's still pretty, though, and holds a lot of jewelry. PRICE-WISE If you're looking at the price and it says $45 or more, don't buy it. I waited a month for the price to go down (I'm just a cheapskate) and it did. It went from $45 or so, down to $25 or so. So, unless its life or death, be patient and buy it when the price is right. OVERALL? In general, I was pleased with the product. It wasn't my dream jewelry stand, but it was worth my money and the wait.
