Nanoneedles formed on an electrocatalyst improve hydrogen production

The low-cost, efficient production of hydrogen is an important step toward developing alternative, clean energy sources. Electrochemical water splitting, which splits water into its hydrogen and oxygen elements using an electrocatalyst, is a viable option for producing hydrogen. Conventionally, catalysts have been based on costly elements such as platinum, which makes it difficult to apply this technology on a widespread, commercial scale.
