In heterogeneous catalysis, medium- to large-pore carbons with a high total pore volume are preferred in order to increase the contact surface between the reactants and the active sites. Nitrogen-doped CNTs lead to the more active support for gas adsorption. Peng and Cho reported that N-CNTs could be used as gas sensors for CO and water while CNTs are not sensitive to these molecules [99].
