Product Overview 

Monatomic catalysts are a class of catalysts in which isolated individual atoms are uniformly dispersed on a carrier without any form of interaction between each individual atom. The active metal in a monatomic catalyst is uniformly dispersed as individual atoms on a carrier, forming a unique coordination environment with the surrounding atoms. Common types of monoatomic catalysts with single atoms include noble metals such as Pt, Pd, Au, Ir, Ag, Rh and non-precious metals such as Fe, Co, Ni, Cu. Commonly used carriers are metals and metal oxides, such as Fe2O3, TiO2 and Al2O3, and carbon-based carriers, such as carbon nanospheres, carbon nanofibres, graphene, metal-organic framework-derived carbon, covalent triazine frameworks, carbon nitride, and phthalocyanine-derived carbon. Preparation methods include high-temperature pyrolysis, impregnation, atomic layer deposition, metal-organic framework derived and electrochemical deposition. The single-atom catalysts provided by Xianfeng are obtained by high-temperature pyrolysis of nitrogen-containing carbon organics (e.g., PVP) to obtain amorphous nitrogen-doped carbon carriers, with the metal atoms using nitrates or chlorides as precursors.

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.

An enjoyable new series with promise
Format: Mass Market Paperback
This is the first in a series. I have already ordered the next one so I like it. The main character Charlie Harris is a widowed library archivist. He lives in his late aunt's house and takes in borders and he owns a Maine coon large cat named Diesel. This is already a somewhat unusual cozy mystery because the main character and devoted cat owner is male. Charlie is a very personable character. He loved his wife (she died of cancer) and his late Aunt. He has 2 grown-up children that he cares about and he likes his job. He gets involved in a murder because his boarder, a young college, student is involved. His archival skills come in handy in providing clues to the murder. The deputy in charge of the investigation is the daughter of his long-time housekeeper. I didn't peek ahead to see who-did-it and I enjoyed the story til the end.. I don't think it's the type of mystery where all the clues are available and the reader tries to figure it out. The reader gets the clues as Charlie . gets them and finds out who the murderer is when Charlie finds out. Yet, the characters are engaging, the setting is interesting and it is a fast and enjoyable read. The plot is credible I like it.

Very good, entertaining mystery.
Format: Mass Market Paperback
I don't know if this author has written other books before beginning this series but it is a very good FIRST in what is so far just a 3 book series. I ordered all 3 but am reading them in order as I always do. The author tends to go into too much detail about mundane things about things like fixing a meal, etc., but it isn't too distracting from the story. I like a little hominess but this is overdone just a tad. The story moved right along establishing characters without throwing in so many that you simply can't keep them all straight as some authors do. A thoroughly despicable victim so nobody cares if he dies violently. And, to me, a reeeely surprise ending. For someone who has read as many mysteries as I have, this was a pleasant surprise and the author doesn't give you hints till you are almost at the reveal so that you feel clever at figuring it out but you don't figure it out too early and you are still a bit surprised that you were "right" about who did it. Also, the "hero" is a thoroughly likeable guy. Don't you hate it when the "hero" or "heroine" just comes across as someone you don't really like much. You know, the one that if he or she gets beat up, you sort of feel like they deserved it and you've not really sorry. Well, if something bad had happened to "Charlie" I'd have been very upset. Now, if #2 will just show up I'll get on with the series. This is a series I'll be keeping in my library to reread in a couple of years.

OK book
Format: Kindle
I read this for our book club, got the book on Kindle, so the "back of the book" description was not there...It took me a while to get into the book. I'm used to female lead characters, and I had to adjust for the lead character to be Mr. Charlie. The manners shown by the characters are a bit dated, by about 40 years, but it's nice to be re-exposed to good manners. Loved Deisel the cat, but whenever he's mentioned (which is a lot) it tells he's a cat. That got to be old, fast. Otherwise, it was a good book, quick read. I was rather shocked to learn that Miranda James is just a pen name for a male writer.
