Amorphous/Crystalline ZrO2 with Oxygen Vacancies Anchored Nano‐Ru Enhance Reverse Hydrogen Spillover in Alkaline Hydrogen Evolution

Hydrogen spillover-based binary (HSBB) system has attracted significant attention in alkaline hydrogen evolution reaction (HER). Accelerating hydrogen spillover in the HSBB system is crucial for the HER activity. Herein, a highly efficient HSBB system is developed by anchoring nano-Ru on oxygen vacancy (Vo) rich amorphous/crystal ZrO
