The production of hydrogen via the catalyst-assisted decomposition of water was investigated under mild conditions for the reaction Zn + H/sub 2/O ..-->.. ZnO + H/sub 2/. Hydrogen yields were determined for reaction temperatures of 303, 333, and 353 K at various time intervals. The extent of reaction completion varied from a few percent to about 95%. The catalyst systems investigated consisted of the following metals electrochemically dispersed on the Zn surface: Ag, Ni, Fe, Au, Pd, Ru, and Rh. Except for Ag and Ni, addition of the other metals to zinc enhanced the production of hydrogen. The order of promoting effect was found to be Rh > Pt > Ru > Pd L Au > Fe > no catalyst > Ni > Ag. Kinetic data obtained closely fit a homogeneous sphere topochemical reaction model.
