Controlling the shape of noble metal nanoparticles is a challenging but important task in electrocatalysis. Apart from hollow and nanocage structures, concave are considered new class unconventional electrocatalysts that exhibit superior electrocatalytic properties as compared with those conventional (including convex flat ones). Herein, several facile highly reproducible routes for synthesizin...

Spin engineering is recognized as a promising strategy that modulates the association between d-orbital electrons and oxygenated species, enhances catalytic kinetics. However, few efforts have been made to clarify whether spin could make considerable enhancement for electrocatalytic water oxidation. Herein, we report of nanocage-structured (Co,Ni)Se2/[email protected], showed significant oxygen...
