Mechanochemical activation of aluminum with gallams for hydrogen evolution from water

A new method has been developed for mechanochemical activation of aluminum: the metal is treated with a gallam, and the “alloy” is processed in a high-energy ball mill. Kinetic parameters of the reaction between activated aluminum and water (hydrogen evolution rate and yield) under standard conditions are presented. The dependences of the hydrogen evolution rate on the composition and amount of the gallam and on the reaction temperature are reported. The storage behavior of activated aluminum has been investigated.
