Carbon dioxide is one of the most important greenhouse gases that is produced by burning fossil fuels. Carbon dioxide capture and separation technologies are an essential method to combat global warming. Coffee is one of the most important agricultural commodities in the world. In this study, a nano-sorbent was made from coffee grounds by controlling particles in mesomicro dimensions. The nano-sorbent was made from washed coffee grounds that were carbonized under nitrogen for 1 hour at 400 °C, then activated with KOH and placed under nitrogen at 850 °C. Then its structure was modified with melamine. BET analysis and carbon dioxide absorption test were performed on the nano-sorbent. The results showed that the use of melamine to modify the structure increased the surface area from 1665 m2/g to 2282 m2/g and the mesopore volume from 0.79 cm3/g to 1.08 cm3/g. Carbon dioxide absorption was also evaluated at atmospheric pressures and ambient temperatures.
