Activating Inert Palmeirite Through Co Local‐Environment Modulation and Spin Electrons Rearrangement for Superior Oxygen Evolution (Adv. Energy Mater. 18/2025)

Oxygen Evolution

In article number 2405555, Jing Sun, Jianan Zhang, Qin Wang, and co-workers present an innovative strategy to anchor thiospinel Co₃S₄ nanoparticles onto the surface of the Co₂Mo₃O₈ nanosheet which can trigger the spin electrons rearrangement, thus activating inert sites. The Co₂Mo₃O₈/Co₃S₄ exhibits remarkable oxygen evolution reaction performance with an overpotential of 227 mV at 10 mA cm⁻².
