Heteroatom-doped carbon materials with expanded interlayer distance have been widely studied as anodes for sodium-ion batteries (SIBs). However, it remains unexplored to further enlarge the spacing and reveal influence of heteroatom doping on nanostructures developing more efficient SIB anode materials. Here, a series N-rich few-layer graphene (N-FLG) tuneable ranging from 0.45 0.51 nm is successfully synthesized by annealing graphitic nitride (g-C3 N4 ) under zinc catalysis selected...
Abstract Engineering high‐energy interfacial structures for high‐performance electrocatalysis is achieved by chemical coupling of active CoO nanoclusters and high‐index facet Mn 3 O 4 nano‐octahedrons (hi‐Mn ). A thorough characterization, including synchrotron‐based near edge X‐ray absorption fine structure, reveals that strong interactions between both components promote the formation Mn‐O‐Co species high oxidation state CoO, from which electrons are drawn III ‐O present in hi‐Mn .
