An old solution to a new problem? Hydrogen generation by the reaction of ferrosilicon with aqueous sodium hydroxide solutions

摘要: The chemical hydrogen storage properties of ferrosilicon were investigated. A yield ~4.75 wt.% (with respect to the mass ferrosilicon) was estimated by reaction varying quantities with 5 mL 40 wt.% sodium hydroxide solution. aqueous solution form found have an activation energy 90.5 kJ mol−1 means Arrhenius plot. It observed that induction period generation varies exponentially temperature. Although this combination high and a lengthy at low temperatures reduces attractiveness for portable applications unless methods can be developed accelerate onset rate generation, its cost widespread availability make it attractive further studies focused on higher temperature stationary applications.
