Adsorption behavior of tetraethylenepentamine-functionalized Si-MCM-41 for CO2 adsorption

Carbon dioxide (CO2) mitigation is of prime importance due to its prodigious release into the atmosphere from power plants and other industrial sources which directly influence the climate change. Adsorption process is considered as an attractive process for CO2 separation and purification due to lo...
