Studies of Carbon Dioxide Capture on Porous Chitosan Derivative

Abstract

Chitosan was modified with 4-formyltriphenylamine to obtain a material with better surface morphology and adsorption profile. Surface morphology and Brunauer–Emmett–Teller (BET) analysis has proved that the chitosan derivative presents higher porosity. CO₂ adsorption analysis results reveal that the triphenyl amine chitosan derivative shows better adsorption than pure chitosan. The results revealed that this material may open new vistas in environmental and industrial applications for carbon dioxide capture, in order to help to reduce the adverse impact of large emissions of the greenhouse gas is the atmosphere.
