Having used fossil fuels for over a century for nearly everything, humanity has triggered a climate crisis. Now, the directive is to achieve net zero emissions or carbon neutrality by 2050.
A hydrogen economy is one way in which a carbon neutral world can thrive. At present, the simplest way to produce hydrogen fuel is electrochemical water splitting: running electricity through water in the presence of catalysts (reaction-enhancing substances) to yield hydrogen and oxygen. This reaction, however, is very slow, requires specialized conditions and noble-metal catalysts, and is overall expensive. Thus, achieving a high hydrogen yield in an energy-efficient manner at low cost is challenging. To date, hydrogen production from water splitting has not been successfully commercialized.
Now, a team of researchers from Pusan National University, Korea, led by Professor Kandasamy Prabakar, have developed a method to design a novel electrocatalyst that can solve some of these problems. Their work was made available online on April 6, 2021, and will be published in print in the September 2021 issue of Volume 292 of Applied Catalysis B: Environmental.
Describing the study, Prof. Prabakar says, "Today, 90% of hydrogen is produced from steam reforming processes that emit greenhouse gases into the atmosphere. In our laboratory, we have developed a non-noble metal based stable electrocatalyst on a polymer support which can effectively produce hydrogen and oxygen from water at a low-cost...
