Researchers from the University of Pittsburgh have developed a nanomaterial with an organometallic structure, which is capable of absorbing carbon dioxide and hydrogen from the air, creating useful chemicals from them.
Currently, there is no economically advantageous and energy efficient method for collecting carbon dioxide from the atmosphere, followed by its transformation into useful carbon-containing compounds. However, American scientists approached the solution of this problem. They created a nanomaterial with an organometallic structure (MOF), which removes CO2 from the air and contributes to its interaction with hydrogen molecules, as a result of which the chemical precursor of methanol is formed — formic acid.
Under normal conditions, such a reaction requires overcoming the energy threshold, but the invention of scientists acts as a catalyst. The nanomaterial bends the geometric structure of the carbon dioxide molecule, thereby contributing to the interaction with hydrogen. In fact, the mof frame activates CO2 and reduces the energy barrier.
The team believes that with further improvement of the product, they will be able to achieve a reduction in greenhouse gas levels in the atmosphere, in parallel turning them into fuel or other useful chemical compounds. They plan to create special filters for chimneys of industrial enterprises and power plants so that the technology can bring real benefits.
No less useful invention presented researchers from the University of Zurich, who developed a new type of nanoparticles for use in
