Chemical engineers at Monash University in Australia have developed an innovative industrial process for producing of acetic acid, also known as vinegar, using the excess carbon dioxide (CO2) present in atmosphere.
This promising technology has the potential to generate negative carbon emissions.

The results of this study were published in the renowned journal Nature Communications, revealing that vinegar can be produced from captured carbon dioxide (CO2) using a low-cost solid catalyst. cost.
This advance makes it possible to replace traditional liquid catalysts based on rhodium or iridium, which are widely used in this process.
As stated by Thankssale, even if all industrial emissions were stopped today, the negative impacts of global warming would persist for at least a thousand years.
Vinegar may be effective against global warming
Akshat Tanksale, the main researcher of this study, points out that this discovery can become an important ally for large industries.
He points out that carbon dioxide (CO₂) is abundant in the atmosphere and is the main cause of global warming and climate change.
Akshat Tanksale stresses the importance of an active approach to removing CO₂ from the atmosphere and converting it into products that don't release it back.
It emphasizes the need to develop an industrially viable method on a large scale to promote negative emissions and address challenges related to climate change.
With the use of this process for producing acetic acid from CO₂, it is possible to contribute to the reduction of these emissions and promote a positive impact on the environment.
Therefore, a team of researchers dedicated themselves to the development of an organic metal structure (MOF), which consists of a crystalline substance composed of repeating units of iron atoms connected by bridges organic.
After this process, the MOF was subjected to careful heating, which resulted in the breakage of the bridges present in the structure. As a result, particles with extremely small dimensions, on the scale of nanometers, were formed, in which the atoms cluster together.
These particles are essential for the efficient functioning of the process of producing acetic acid from captured CO₂.
After the formation of iron particles, these nanoparticles were embedded in a porous layer of carbon. This structure provided stability to the iron particles during chemical reactions, making them active in the acetic acid production process.
This approach resulted in the development of the first iron-based catalyst with a specific focus on acetic acid production.
In addition to the advantages of greater efficiency and economy compared to liquid catalysts, solid catalysts Developed countries also have significant potential to inhibit global warming, helping to slow down global change. weather.
