Enhancing Hydrogen Production with Nanoneedles on Electrocatalysts

Researchers have developed a new method to improve the efficiency of electrocatalysts for hydrogen production. By adding molybdenum to a nickel-cobalt phosphide catalyst and using a gradient hydrothermal process, nanoneedles were formed on the catalyst's surface, creating a unique microstructure. This microstructure enhanced electron transfer and the release of hydrogen bubbles, resulting in improved performance. The catalyst showed stability and reliability over 100 hours of testing, and future studies will explore its application in different solutions and alternative substrates.
