Herein, we investigated a novel carbon contained highly microporous/mesoporous copolymer P123 activated boron nitride whiskers (P123-CBNW) fabricated via structure directing approach followed by single step heat treatment under N2 atmosphere. The influence of an activating agent (P123 copolymer) and melamine on adsorption efficiency of CO2 has been reported. The maximum CO2 uptakes tendency of prepared adsorbents was at 273 K, 283 K, 298 K at 1bar pressure, with high isosteric heat of adsorption. Extensive analysis exposes that the presence of carbon contents, high specific surface area, high microporosity, chemically structure defects within the P123-CBNW adsorbents responsible for raising the CO2 adsorption tendency and the selectivity over N2 gas. |
