Nano-flower-shaped Ru-NiFeAl-LDHs@rGO for efficient hydrogen evolution reaction and oxygen evolution reaction
Source abstract
Abstract
Pt/C is currently widely utilized as a catalyst for electrolytic hydrogen production. However, the high cost of Pt-based catalysts limits further development. Therefore, developing an efficient, highly stable, and cost-effective catalyst is crucial. In this study, we enhanced the ability to activate H 2O and the performance of the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) by incorporating a small amount of Ru into NiFeAl-layered double hydroxides (LDHs), thereby altering the electrochemical active surface area and the catalysts’ internal resistance. The catalyst demonstrated excellent catalytic activity in alkaline electrolytes, achieving low overpotentials of 33 mV at 10 mA cm −2 and 278 mV at 50 mA cm −2. Furthermore, it demonstrated outstanding stability for up to 240 h; the catalyst was successfully assembled into a solar-powered hydrogen production system via full-water-splitting testing, thus providing more possibilities for electrolytic hydrogen production.
