Environmental sustainability: a proposal based on CO2 removal and advanced material synthesis

Abstract

The concern of scientists and climatologists that high greenhouse gas emissions are on the rise, causing the earth's surface to warm at a very rapid rate (Maring & Webley, 2013), have required solutions and technologies to reduce these emissions. By capturing, storing and transforming carbon dioxide (CO₂), there is an opportunity to reduce emissions into the atmosphere and mitigate related problems. The following research describes the processes that were carried out to adsorb CO₂, starting with the synthesis of mesoporous silica (SBA-15). MgO, Mg (OH)₂, CaO y Ca (OH)₂ in proportions of 5%, 10% and 15%, were impregnated in SBA-15, continuing with the studies to know that the impregnation was correct and to continue the adsorption process. According to the results and analyzing the samples of MgO, Mg (OH)₂, CaO y Ca (OH)₂, which are supported in the SBA-15, those with the highest CO₂ adsorption are magnesium, which increases the higher the proportion of impregnation for 15% MgO, 4.5 mmol/g and 4.1 mmol/g for 15% Mg(OH)₂.
