摘要：

Microporous carbons were prepared from coconut shell by one-step activation with CO2. The specific surface area and micropore volume were tuned from 686 to 1327 m(2)/g and from 0.31 to 0.65 cm(3)/g, respectively, by varying time of CO2 activation. The maximum adsorption of CO2 on these carbons at 760 mmHg reached the values 3.9 and 5.6 mmol/g at 25 and 0 degrees C, respectively, which are comparable to the reported values of CO2 adsorption capacity on vegetable origin carbons.
