The key disadvantage of silicon oxidation is its relative inefficiency. The energy input required to create the silicon nanoparticles is much greater than the energy available from the hydrogen that is finally produced. For large scale applications, this would be a problem. For portable applications, it is not. For example, the cost of electricity supplied by an ordinary household battery can easily be 10 to 100 times higher than the cost of electricity from a utility, but batteries still play an important role in our lives."
And the next two final paragraphs:
In the future, the researchers plan to further increase the hydrogen generation capacity of silicon oxidation by experimenting with different mixtures.
"One direction that we are presently pursuing is the use of mixtures of silicon nanoparticles with metal hydrides, which also react with water to produce hydrogen," Swihart said. "Compounds like lithium hydride and sodium hydride react with water to produce the base (LiOH or NaOH) that is needed to catalyze the silicon oxidation. However, they can react too fast with water (explosively) and are not stable in air. Mixing them with silicon nanoparticles or coating them with silicon nanoparticles may serve to both temper their reactivity and increase the hydrogen generation capacity of the system by replacing the added base (e.g., KOH in the published paper) with a material that also generates hydrogen."
*Note : This article was from 2013. Silicon nano-powders or coating them with silicon nanoparticles.... Purevap NSiR reactor says hello
Going to be very interesting next 5-6 weeks.
Long and strong HPQ!
