The Cover Feature illustrates the three dimensional porous architecture (PA@Rh‐uNPs/GA) of graphene aerogel nanocomposites modified by polyamine (PA) and ultrafine rhodium nanoparticles (Rh‐uNPs). Thanks to the ultrafine size of Rh uNPs and the enrichment concentration of the reactants by free amine groups at PA molecules on the surface of PA@Rh‐uNPs/GA nanocomposites, the molecular weight‐optimized PA@Rh‐uNPs/GA nanocomposites with 10 % Rh mass reveal outstanding hydrogen evolution reaction activity in a wide pH range.
