Prussian blue analogs are well suited for sodium‐ion battery cathode materials due to their cheap cost and high theoretical specific capacity. NaxCoFe(CN)6 (CoHCF), one of the PBAs, has poor rate performance and cycling stability, while NaxFeFe(CN)6 (FeHCF) has better rate and cycling performance. The CoHCF@FeHCF core–shell structure is designed with CoHCF as the core material and FeHCF as the shell...
Developing efficient and robust metal–nitrogen–carbon electrocatalysts for oxygen reduction reaction (ORR) is of great significance for the application of hydrogen–oxygen fuel cells and metal–air batteries. Herein, a coordination engineering strategy is developed to improve the ORR kinetics and stability of cobalt–nitrogen–carbon (Co–N–C) electrocatalysts by grafting the oxygen‐rich graphene quantum...
Electrochemical Nc reduction has been regarded as one of the most promising approaches to producing ammonia under mild conditions, but there are remaining pressing challenges in improving the reaction rate and efficiency. Herein, an unconventional galvanic replacement reaction is reported to fabricate a unique hierarchical structure composed of Fe3O4‐CeO2 bimetallic nanotubes covered by Fe2O3 ultrathin...
Near‐infrared (NIR) light‐triggered hyperthermia has exhibited promising prospects in oncology therapy due to the unique merits including minimal invasiveness, monitorable, excellent therapeutic effect, and negligible side effects. Especially, the second NIR biowindow (NIR‐II, 1000–1700 nm) with less absorbance and scattering by skin tissue, and deep tissue penetration, has received extensive attention...
