When faced with the inevitability of the Hydrogen Economy, naysayers, curmudgeons and Luddites cling to the old saw about the efficiencies of hydrolysis...however, each and every day more direct, newer and more efficient technologies emerge to deliver a steady flow of the precious gas!

Mimicking butterfly wings could boost hydrogen fuel production

Quote:
So, what does this have to do with fuel cells? Splitting water into hydrogen and oxygen takes energy, and is a drain on the amount you can get out of a cell. To split the water, the process uses a catalyst, and certain catalysts say, titanium dioxide function by exposure to light. The researchers synthesized a titanium dioxide catalyst using the pattern from the butterfly's wings, and paired it with platinum nanoparticles to make it more efficient at splitting water. The result? A 230% uptick in the amount of hydrogen produced. The structure of the butterfly's wing means that it's better at absorbing light so who knows, you might also see the same technique on solar panels, too.
