Prussian blue analogues (PBAs) are recognized as promising cathode materials for sodium‐ion batteries (SIBs) due to their facile synthesis, low‐cost, high capacity, and environmental friendliness. However, high water content (>10 wt%) in the framework and unsatisfactory structural stability of PBAs are still the bottlenecks for industrial applications. Herein, interstitial K‐doping is employed...
Constructing heterostructures is an efficient strategy to develop high‐performance and robust electrocatalysts for oxygen evolution reaction (OER). Herein, an ion‐impregnation method and an environmentally friendly in situ carbonization strategy are successively employed to fabricate a novel Co3Mo/Mo2C heterostructure anchored on nitrogen‐doped carbon (Co3Mo/Mo2C@NC). Thanks to the formation of heterostructure,...
