    Artificial photosynthesis converts carbon dioxide to propane

    Artificial Photosynthesis System as efficient as plants and can reduce CO2 levels #DigInfo

    A team of chemists has developed a technology for the production of liquefied fuel from water, carbon dioxide and visible light through artificial photosynthesis.

    Plants use solar energy to stimulate chemical reactions between H2O and CO2 in order to synthesize glucose. In a new study, scientists described an artificial process that uses the same raw materials as plants to convert water and carbon dioxide into more complex hydrocarbon molecules like propane..

    The role of chlorophyll in the laboratory was played by metal catalysts with electron-enriched gold nanoparticles that absorbed green light and transported the elementary particles needed for the chemical reaction between water and carbon dioxide. Gold interacts well with carbon dioxide and absorbs energy without being destroyed like other metals.

     

    Scientists from the University of Illinois say that liquefied fuel is safer than gaseous fuel, it is cheaper and easier to transport, and its molecules contain more bonds, that is, the energy is packed more densely in them. In their opinion, it is better not to burn the hydrocarbons obtained in this way, but to convert them into fuel cells for the production of electricity..

    Artificial photosynthesis converts carbon dioxide into propane

    Despite the potential of green energy technology, researchers recognize that natural photosynthesis in plants is still far more efficient than the artificial process invented. Therefore, they will continue to improve the catalyst to make the method economically feasible..

    Recently, an international team of researchers developed method for efficiently converting carbon dioxide into coal at room temperature.
