Researchers from the University of Twente, in collaboration with Shell, have developed a new mechanism that converts carbon dioxide into carbon monoxide, which is an essential ingredient in chemical production.
In this range project Under the auspices of the Association of Advanced Research Centers for Chemical Building Blocks (ARC CBBC), the researchers published their findings in the journal Nature. Energy letter ACS. Their publication was also chosen for the cover of the same magazine. UT Ph.D. student and lead author Sobhan Neyrizi states, “With the new molecules engineered in our study, we can innovate a new pathway for CO2 convert. “
The emanation of carbon dioxide is considered one of the main causes of global warming. One possible solution is the electrochemical conversion of carbon dioxide into more useful molecules such as carbon monoxide, formic acid and hydrocarbons, which are important intermediates in the production of fuels and chemicals. However, the energy requirement of the reaction is still too high.
New road
New molecules that Sobhan Neyrizi and his fellow researchers have developed may aid in the electrochemical conversion of carbon dioxide.
“Our molecules act as a co-catalyst reducing the energy requirement of the reaction to a large extent,” Neyrizi said. The researchers think they can use these molecules to innovate a new pathway for the reaction. “We can also recommend design principles to develop more efficient molecules in the future. “
100% effective
In electrochemistry, electrons are used as an inexpensive source of energy. But converting electrons to carbon dioxide – the crucial step required for the conversion – requires too much energy. The required energy can be drastically reduced by simultaneously transferring protons and electrons to carbon dioxide molecules.
The co-catalysts are designed to make this simultaneous transmission possible on the gold surface. “We can achieve 100% conversion efficiency, which means all electronic Neyrizi explained.
