In addition to the support, the active phase can also be promoted by adding an alkali metal [21]. Indeed the addition of alkali metals has repeatedly shown to improve CO2 adsorption, as the presence of these species significantly modifies the electronic density of the catalyst's surface as ...
Introduction Tin and its compounds can be applied in many industries, such as soldering, plating, alloy, chemistry, and metallurgy [1]. The global tin resources with industrial utilization value are mainly derived from cassiterite (SnO2), some of which contain a significant amount of slime (clay...
