Can hydrogen be produced from water?
Efficiently mass-producing hydrogen from water is closer to becoming a reality thanks to Oregon State University College of Engineering researchers and collaborators at Cornell University and the Argonne National Laboratory.
The scientists used advanced experimental tools to forge a clearer understanding of an electrochemical catalytic process that's cleaner and more sustainable than deriving hydrogen from natural gas.
Findings were published today in Science Advances.
Hydrogen is found in a wide range of compounds on Earth, most commonly combining with oxygen to make water, and it has many scientific, industrial and energy-related roles. It also occurs in the form of hydrocarbons, compounds consisting of hydrogen and carbon such as methane, the primary component of natural gas.
"The production of hydrogen is important for many aspects of our life, such as fuel cells for cars and the manufacture of many useful chemicals such as ammonia," said Oregon State's Zhenxing Feng, a chemical engineering professor who led the study. "It's also used in the refining of metals, for producing human-made materials such as plastics and for a range of other purposes."
According to the Department of Energy, the United States produces most of its hydrogen from a methane sourc
