The nickel-metal/nickel-oxide catalyst, discovered by Stanford graduate student Ming Gong, also requires significantly lower voltages to split water when compared to pure nickel or pure nickel oxide. This new technique is not quite ready for commercial production, though.

"The electrodes are fairly stable, but they do slowly decay over time," Gong says. "The current device would probably run for days, but weeks or months would be preferable. That goal is achievable based on my most recent results."
