Although the electron‐withdrawing effect of gold (Au) is highlighted in catalytic reactions, its enhancement mechanism for electron transport, especially in the electrochemical process, is still unclear. Herein, Au‐decorated Bi2O3 (Au‐Bi2O3) is proposed as a proof‐of‐concept to investigate the electron‐withdrawing effect in the electrocatalytic CO2 reduction reaction (eCO2RR) process. Evidence from...
Introducing heteroatoms into atomically dispersed Fe–N4 sites with symmetric electron distribution can adjust the imperfect oxygenated adsorption‐activation and promote oxygen reduction reaction (ORR) activity. However, the relevant design synthesis and deeply understanding the electrocatalytic mechanism of such an asymmetric structure by introducing Fe–C coordination remains challenging. Herein,...
Zinc–air batteries (ZABs) exhibit high energy density as well as flexibility, safety, and portability, thereby fulfilling the requirements of power batteries and consumer batteries. However, the limited efficiency and stability are still the significant challenge. Oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are two crucial cathode reactions in ZABs. Development of bifunctional...
Development of efficient and durable non‐Pt catalysts for hydrogen evolution reaction (HER) in acid media is highly desirable. Iron nitride has emerged as a promising catalyst for its cost‐effective nature, but the corresponding acidic stability must be promoted. Herein, phosphorus‐decorated Fe2N and reduced graphene oxide (P‐Fe2N/rGO) composite are designed and synthesized. X‐ray photoelectron spectroscopy...
Fabricating cost‐effective, bifunctional electrocatalysts for both the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in basic media is critical for renewable energy generation. Here, NiSe/CP, Ni0.85Se/CP, and NiSe‐Ni0.85Se/CP heterostructure catalysts with different phase constitutions are successfully prepared through in situ selenylation of a NiO nanoflake array oriented...
