What are the main iron based catalysts used for?5 answersIron-based catalysts are used for various purposes. They are commonly used in the Fischer-Tropsch synthesis for the production of hydrocarbons from synthesis gas. Iron-based catalysts are also used in the synthesis of light olefins via the Fischer-Tropsch to olefins (FTO) reaction. Additionally, iron-based catalysts have shown promise in the direct hydrogenation reactions of carbon dioxide (CO2) to olefins. In the field of water treatment, iron-based catalysts have been employed in catalytic ozone oxidation processes for the degradation of organic pollutants. These catalysts have been studied for their catalytic efficiencies and the activation mechanisms of hydroxyl radicals in the ozone system. Overall, iron-based catalysts have a wide range of applications including hydrocarbon synthesis, carbon dioxide hydrogenation, and water treatment processes.
How do cobalt catalysts work?5 answersCobalt catalysts work by facilitating various chemical reactions. They can be used in the selective hydrogenation of carbon dioxide (CO2) into value-added chemicals, such as methane, methanol, and C2+ alcohols. Cobalt catalysts also enable the synthesis of substituted alkynylsilanes through dehydrogenative coupling of alkynylsilanes and hydrosilanes. In addition, cobalt-based catalysts are effective for the reduction of CO2, but they also show low free energy of hydrogen evolution reaction (HER), making HER competitive with CO2 reduction. To improve the selectivity of CO2 reduction while maintaining catalytic efficiency, rare earth (RE) compounds, such as Er2O3 and ErF3, can be used. These compounds promote charge transfer, mediate the reaction paths of CO2 reduction and HER, and increase the CO selectivity of cobalt catalysts. Cobalt catalysts can also be used in the synthesis of 1H-perimidines from dinitroarenes and aldehydes through hydrogenation reactions.
