Abstract
The development of efficient and competitive acidic oxygen evolution reaction (OER) electrocatalysts is a major challenge for hydrogen production by water electrolysis. In this paper, a novel strategy was proposed for preparing OER electrode material, by which a polyphenol (ppl) film was plated on a carbon black-coated nickel foam substrate. The electrode Ni/C-ppl-30-0.1-0.1 shows excellent catalytic activity and stability. The overpotential at 10 mA cm−2 is 350 mV, which is lower than some of the reported non-precious metal materials. Structural and electrocatalytic performance analyses show that the performance of the electrode benefits from the surface defects of the ppl film and the abundant oxygen-containing functional group, which provide numerous catalytic centers for OER. This work provides an attempt to enhance the anodic stability in acidic media by conductive polymer film.
期刊介绍:
The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc.
The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
