Effect of carbonization temperature on the physical properties and CO2 adsorption behavior of petroleum coke-derived porous carbon

[Display omitted] •Petroleum coke was used to prepare porous carbons for CO2 capture.•Carbonization changes structural disorder and amount of surface functional groups.•Optimal carbonization temperature exits for the maximum porosity.•CO2 uptakes have strong correlation with narrow micropores (...
