3Dprinting monoatomic catalysts
What if a substance that converted CO into fertilizer from sewage could be 3D printed it into usable materials once more and successfully create hydrogen fuel from water?
And last but not least, what if you could do it on a budget? It is all feasible, but expensive.
Currently, a simple and affordable 3D printing method for “monatomic catalysts” has been created by an international team of scientists.
These substances, like all catalysts, speed up and use less energy during chemical reactions.
Monatomic catalysts, however, are particularly intriguing because reactions can be carried out with even less energy and waste thanks to their high efficiency.
Monatomic catalysts contain multiple atoms. They are individual metal atoms that have been embedded in a substance, typically on a very small solid scaffold.
Because the metal atoms are dispersed and do not vie with one another,
each one can perform its task as effectively as possible, converting reagent molecules into products.
According to Professor Shizhang Qiao, director of the University of Adelaide’s Center for Materials in Energy and Catalysis and the paper’s lead author, “This unique advantage drives my research team to study this new type of catalyst.”
3D printing Monatomic catalysts
Monatomic catalyst production has previously been very pricey and difficult.
However, Qiao and associates have demonstrated that they can be produced in a matter of minutes using a 3D printer.
The scaffolding was constructed using a 3D bioprinter.
Both metals and natural polymers were present in the printing ink.

The majority of these natural polymers are widely available, according to Qiao.
This gives me hope that other researchers will be able to spot this procedure with ease.
When the scaffolds were finished, researchers at Australia’s Synchrotron used X-ray spectroscopy to demonstrate that they contained individual atoms.
The technique was then put to the test by Qiao and colleagues, who produced a group of monatomic catalysts that are intended to turn wastewater nitrates into ammonia.
Ammonia is a crucial component of fertilizers, medicines, and a variety of other products. As it can assist in storing hydrogen fuel, it is also anticipated to play a significant role in the energy sector over the next three decades.
On the other hand, monatomic catalysts might be able to help with a lot of other processes.
According to Qiao, his research team used various electrocatalysts in various reactions.
For instance, they created a new kind of catalyst for oxidizing urea-rich wastewater and producing hydrogen from water splitting, reducing carbon dioxide to create useful chemicals and fuels, and reducing oxygen in fuel cells.
“All of these applications are advantageous for the technology of renewable energy.”
Monatomic catalysts may be made available to the chemical industry within the next ten years, according to scientists.
