Abstract
The invention relates to the use of nonpassivated silicon to produce hydrogen, by hydrolysis of the nonpassivated silicon. In particular, the invention relates to a composition comprising nonpassivated silicon, a process for producing a composition comprising nonpassivated silicon, and a process for producing hydrogen by reacting the composition with water.
Claims55
A composition which comprises an intimate mixture of:
- (a) nonpassivated silicon;
- and
- (b) a dispersing agent which is a water-soluble molecular compound,
- a dispersant which is a water-soluble ionic compound having a heat of solution in water more negative than −40 kJmol−1, or
- a colloidal stabilizer which is a water-soluble polyelectrolyte.
