Defect-rich engineering and F dopant Co-modulated NiO hollow dendritic skeleton as a self-supported electrode for high-current density hydrogen evolution reaction

Exploring the low-cost and high-efficient electrocatalysts with Pt-like activity for alkaline hydrogen evolution through water splitting is imperative yet challenging. Herein, a simple synthesis combined with electrodeposition and facile electro-oxidation is developed to construct the hollow dendritic self-supported electrode (HDSE). X-ray photoelectron spectroscopy (XPS), X-ray absorption fine structure (XAFS), and electron paramagnetic...
