Nanosilicon rapidly splits water without light, heat, or electricity

Illustration of the multidisciplinary approach for producing hydrogen through silicon oxidation. The approach involves synthesizing silicon nanoparticles, the silicon-water reaction which generates hydrogen on demand, and using the hydrogen in a fuel cell for portable power.

(Phys.org)—Although scientists know that when silicon mixes with water, hydrogen is produced through oxidation, no one expected how quickly silicon nanoparticles might perform this task. As a new study has revealed, 10-nm silicon nanoparticles can generate hydrogen 150 times faster than 100-nm silicon nanoparticles, and 1,000 times faster than bulk silicon. The discovery could pave the way toward rapid "just add water" hydrogen generation technologies for portable devices without the need for light, heat, or electricity.
