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.

Another Thanks and Wow by Anne Lamott!
Format: Hardcover
I was first introduced to Anne Lamott's writing about 25 years ago when I read her book, Bird by Bird. It was a book about how to write and from that moment she became one of my favorite authors. Help, Thanks, Wow is a wonderful book that I have underlined and reread over and over again. Her writing has a voice that many of us can relate to. It's honest and you can feel her pain. She writes with humor to balance the good with the bad. Something that is so important to learn as we go through life. Her descriptions help you see, feel, and smell when she describes "autumn...the colors are broccoli and flame and fox fur. The tang is apples. The rot smells faintly of grapes..." She tells us how to ask for help when you can't do it all by yourself, but how important it is to say thank you, thank you, thank you and Wow for all the things you are grateful for. I loved when she wrote about how service to others is joy ,but how important it is to be kind to yourself. One of my favorite passages was this one, "This morning at six when I awoke, loneliness was sitting on my chest like a dental X-ray apron, even though I was buried in hairy dog love. Help, I am sad and lonely, and already it looks like today is going to be too long. I prayed...I did a kindness to myself, as I would have a troubled friend..." Her descriptions are all like this one and easy to relate to. I loved this book and have given it to friends who have then bought it for other friends. It is definitely a WOW!!!!

Not bad, but not my cup of tea
Format: Hardcover
After seeing Anne Lamott on TV, I was impressed with her and checked out this book on Amazon. The reviews were good, so I ordered it. I was a bit disappointed on receiving it, as I didn't like the shape of the book (too small) and I didn't like the type style (too hard to read). Then, I struggled to get into the book. I like to highlight insights in inspirational books, and I simply didn't find anything to highlight in this one. I think Anne Lamott is a lovely person and I understand how a lot of people liked this book. However, it just didn't bring any new insights to the table for me and it wasn't written in a way that I found compelling. The good news is, it wasn't too hard to finish, since it is short. I passed it on to someone I hope will enjoy it.

I Just Want to Read It Again!
Format: Hardcover
***** What a brilliant book! When I first received "Help, Thanks, Wow: The Three Essential Prayers" I too was so disappointed that it was such a small book--tiny, short, maybe an hour's read. Ah, but what an hour! Precious. And to be completely truthful, this book actually took me several hours to read, because I had to put it down, think, cry, laugh, and even--yes--pray. This book is worth your time and attention. I am so glad that I have it in hardback because I will keep it forever and reread it regularly; I am finished reading it and I just want to read it all over again. It is a book about getting through life. It is rich, raw, funny (hilarious, like all Annie Lamott) and written in language so stunning I would have to stop and just read and reread sentences. I feel as though my life has been broken open with a whole new attitude towards prayer, and even more, towards being alive. This is not a religious book at all, but a book for anyone who is spiritually-oriented and maybe especially for those who aren't, because the author writes about prayer in a way that every single person can relate to. This is a book about being real and true and simple and clear and about living a worthwhile life. Don't miss this book. Highly recommended. *****

It’s great for the bathroom.
Color: Gold-aa
It’s great. I use it in all my bathrooms. It’s easy to change the paper. It fits on the tank and dresses it up.

Good Product, Fair Price
Color: Gold-aa
I bought this for my guest bathroom where I have some other brass items and it fits right in. Easy assembly with the supplied Allen wrench and bolt, and it comes with a cover for the bolt hole which perfectly matches the base padding material so the assembly point becomes invisible. It doesn’t have a ‘towel unroll preventer’ but I knew that when I evaluated the reasonable sale price and decided that wasn’t important for the intended use. The base is heavy and the assembled item seems very sturdy. I found it weird that this towel holder came with a plastic box containing a fork and a spoon as a ‘gift’ but this will go in my car camping cookware bag. I don’t know how the brass finish will hold up over time but for now I’m very pleased.
