Abstract
Climate change driven by greenhouse gases emissions demands urgent action. Among the strategies currently investigated to curb greenhouse gases concentrations in the atmosphere, CO2 adsorption and valorization are raising increasing interest. Polyaniline (PANI)-based materials have showed high affinity for CO2, due to their nitrogen content, and can thus be used as reversible adsorbents for CO2 removal from gaseous effluents. Pristine PANI, PANI composites and PANI derived carbons have been recently investigated as alternative candidate to traditional materials. In this review, the properties of PANI and its main synthetic methods are briefly described, then an overview of the main classes of PANI-based materials used for CO2 sorption and valorization is presented in order to stimulate further investigation that can contribute to widen the information on the unique properties of this polymer.File | Dimensione | Formato | |
