A new type of Fe, N-doped hierarchically porous carbons (N–Fe-HPCs) has been synthesized via a cost-effective synthetic route, derived from nitrogen-enriched polyquaternium networks by combining a simple silicate templated two-step graphitization of the impregnated carbon. The as-prepared N–Fe-HPCs present a high catalytic activity for the oxygen reduction reaction (ORR) with onset and half-wave potentials of 0.99 and 0.86 V in 0.1 M KOH, respectively, which are superior to commercially available Pt/C catalyst (half-wave potential 0.86 V vs. RHE). Surprisingly, the diffusion-limited current density of N–S-HPCs approaches ∼7.5 mA cm−2, much higher than that of Pt/C (∼5.5 mA cm−2). As a cathode electrode material used in Zn–air batteries, the unique configuration of the N–Fe-HPCs delivers a high discharge peak power density reaching up to 540 mW cm−2 with a current density of 319 mA cm−2 at 1.0 V of cell voltage and an energy density >800 Wh kg−1. Additionally, outstanding ORR durability of the N–Fe-HPCs is demonstrated, as evaluated by the transient cell-voltage behavior of the Zn–air battery retaining an open circuit voltage of 1.48 V over 10 hours with a discharge current density of 100 mA cm−2.

Physical Chemistry Chemical Physics

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.
