Abstract:
Here, we report the synthesis of nitrogen-doped hollow carbon nanospheres (N-HCSs) via a two-step Stöber method. The resultant N-HCSs possess a uniform size of ∼220 nm, a high nitrogen loading content of 14.8 wt% and a high surface area of 767 m(2) g(-1), as well as exhibit a considerable performance for CO2 capture with a capacity of 2.67 mmol g(-1) and a high selectivity in a mixture gas (N2 or O2).
