Abstract
In article number https://doi.org/10.1002/advs.201902126, Yumeng Shi, N. Raveendran Shiju, and co‐workers summarize the types of active sites reported for several mainstream nanocarbons, including carbon nanotubes, graphene‐based materials, and 3D porous nanocarbons. Knowledge about the active sites will be beneficial for the design and synthesis of nanocarbon catalysts with improved activity, selectivity, and stability.

Keywords: edge sites and topological defects, heteroatom doping, M–Nx–C, nanocarbon catalysts, surface functionalization
