Abstract
- To solve the problem of renewable energy generation fluctuation, water splitting for hydrogen generation is proposed, which can store renewable energy as hydrogen energy. Low overpotential cathode materials can effectively reduce the cost of hydrogen production. Here, a new NiMo/NMF electrode was prepared using a hydrothermal coupled H 2 reduction method. Three-dimensional NiMo nanorod arrays were constructed by modulating the ion dissolution and surface epitaxial growth process of the electrode substrate. The influence of different hydrothermal reaction and H 2 reduction conditions on the electrochemical performance of the electrode was investigated. Under optimum preparation conditions, the NiMo/NMF electrode exhibits a extremely low overpotentials of 158 mV at 500 mA cm-2 (30% wt. KOH alkaline medium), which can serve for preparing high efficiency and economy electrodes by in-situ integration of high active components on metal foam substrate. The NiMo/NMF electrode is a high-performance electrocatalytic cathode material with great prospects for industrial applications. • Water splitting for hydrogen generation is proposed for renewable hydrogen energy. • We made a low-overpotential NiMo/NMF electrode via hydrothermal coupled H 2 reduction. • The electrochemical performance of the NiMo/NMF electrode was investigated. • Different hydrothermal and H 2 reduction temperatures and times were explored. • The NiMo/NMF electrode exhibits a remarkable HER activity with low overpotentials.
