The Cover shows a Chinese Terra‐Cotta Warrior and carbon nanotube catalyzed ethylbenzene direct dehydrogenation reactions. Just like the armor to enhance the battle capacity of the warrior, surface modification would promote the catalytic activity of nano‐carbon materials. In their Full Paper, S. Tian et al. explain that the dehydrogenation catalytic activity of carbon nanotube could be enhanced via partial coating with polydopamine polymers. Kinetic and structural analysis results indicate that the nature of the promotion effect relies on the electron transfer from polydopamine dopant to carbon nanotube matrix. More information can be found in the Full Paper by S. Tian et al. on page 2073 in Issue 8, 2019 (DOI: 10.1002/cctc.201900146).
