Abstract
Carbon dioxide (CO2) is a gas that is very influential on global warming, which is about 60%. The gas was emission in large quantities from the burning fuel. The concentration of carbon dioxide in the atmosphere at this time is nearly 400 ppm. Therefore, the problem of carbon gas needs to be immediately solved. So, the greenhouse effect is reduced and leads to the reduction of global warming. Oxygen (O2) is one of the compounds required by humans in their respiratory system. Earth's oxygen content was 20.9% of free air in the atmosphere. However, as time goes by, oxygen levels in the world have dwindled due to global warming caused by pollution in the industrial gases or emissions from motor vehicles. These problems require a material to separate CO2 and O2, which O2 content must be higher to improve the quality of clean air. In this case, one of the things that can improve the quality of air is the utilization of zeolite carbon-based membranes. Zeolites can capture CO2 by adsorption. Some materials used to adsorb CO2 gas include carbon, zeolites, regular mesoporous silica, and metal-organic frameworks. These materials, the most potential in the adsorption of carbon gases such as CO2 are zeolites and carbon. Zeolite is an aluminous-silicate material that has high porosity. The pores on the surface of the zeolite can be adjusted as needed, both micropores (<2nm) and mesoporous (2-5-nm) and these proses are well distributed. So, the utilization of zeolite membrane housed can improve air quality.
