The electronic structure study of carbon nanotube–graphene complexes has been performed using comprehensive X-ray absorption spectroscopy (XAS) at Fe L- and K-edges, along with C, N and O K-edges. The results obtained from the study of an iron-containing carbon nanotube–graphene complex (NT–G) have been compared in great detail with those of an iron-free carbon nanotube–graphene complex (pNT–G) and iron phthalocyanine (FePc). It has been confirmed that complex-like Fe3+ in a high spin state is the major iron component in NT–G. The C and N K-edge XANES further confirmed that Fe is very likely to be bonded to N in NT–G. This Fe–N species should be the active site for enhanced oxygen reduction reaction (ORR) activity in NT–G. A unique O K-edge X-ray absorption spectroscopic feature has been observed in NT–G, which might be caused by chemisorbed O2 on the Fe–N site. Such knowledge is important for the understanding of this specific complex, and the knowledge should benefit the rational design of other carbon/metal/nitrogen-containing ORR catalysts with further improved performance.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
