Zusammenfassung:Method of preparing a compound of formula SinH2n+2 in which n is an integer greater than or equal to 1 and less than or equal to 4, by reaction of at least one silicide or silicon alloy in the form of powder of formula M1xM2ySiz, in which M1 is a reducing metal, M2 an alkali or alkaline-earth metal, x, y and z varying from 0 to 1, z being different from 0 and x+y different from 0, with an aqueous solution comprising CO2, said solution is or is not saturated with CO2 at the temperature and pressure of the reaction.
