A novel carbon contained copolymer P123 activated boron nitride whiskers (P123-CBNW) fabricated via structure directing approach. 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 (136 mg/g, 232 mg/g and 270 mg/g) at 273 K/1 bar and (97 mg/g, 134 mg/g and 155 mg/g) at 298 K/1 bar for CBNW, P123-CBNW1 and P123-CBNW2 adsorbents respectively, 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. |
