zinc is preferred for the preparation of hydrogen from water over pure zinc because the impurity present in granulated zinc is copper whose catalysing effect speeds up the rate of reaction.

Potassium can be used to obtain hydrogen from cold water.
Calcium can be used.
Ca+2H2O--------->Ca(OH)2 + H2.
