Title: Effect of ZnCl{sub 2} activation on CO{sub 2} adsorption of N-doped nanoporous carbons from polypyrrole

Abstract

In this study, N-doping nanoporous carbons (NNCs) were prepared from polypyrrole (PPY) by ZnCl{sub 2} activation. The activation process was carried out under set conditions (PPY/ZnCl{sub 2}=1/4) at 300–800 °C for 2 h. With increasing activation temperature, the specific surface area and total pore volume of the NNCs increased significantly from 539 m{sup 2}/g (300 °C) to 1268 m{sup 2}/g (700 °C) and from 0.245 cm{sup 3}/g (300 °C) to 0.561 cm{sup 3}/g (700 °C), respectively. In addition, the use of PPY carbon precursors allowed the integration of high N content (9.28 wt%) and resulted in a large narrow micropore distribution (<1 nm) in the prepared NNCs. The CO{sub 2} adsorption isotherms showed that PZ-600 exhibited the best CO{sub 2} adsorption capacity of 167 mg/g at 1 bar and 25 °C when the activation temperature was 600 °C. - Graphical abstract: CO{sub 2}/298 K adsorption/desorption isotherms of the N-enriched porous carbons. - Highlights: • N-doping nanoporous carbons were prepared from polypyrrole by ZnCl{sub 2} activation. • Through ZnCl{sub 2} activation, the specific surface area and total pore volume increased. • PZ-600 exhibited the best CO{sub 2} adsorption capacity of 167 mg/g at 1 bar and 25 °C.
