A new process to obtain H(2) from H(2)O using Al corrosion in Na(2)SnO(3) solutions is described. Results showed an enhancement of H(2) production rates using Na(2)SnO(3) instead of NaOH at the same pH. A side reaction of Al in Na(2)SnO(3) solutions has been found, which consumes Al to produce metallic Sn. H(2) yield depends chiefly on Al/Na(2)SnO(3) molar ratio for experiments with Na(2)SnO(3) concentrations above 0.025 M, reaching higher yields with higher Al/Na(2)SnO(3) ratios. The maximum H(2) production rates are proportional to the initially added Al mass. Two different shrinking core models for examining the kinetics of H(2) generation are verified and the activation energy (E(a)) is 73 +/- 6 kJ mol(-1), confirming a rate control by a chemical step. A mechanism of Al corrosion in Na(2)SnO(3) solutions is proposed and compared with the mechanism in NaOH and NaAlO(2) solutions. (C) 2009 Professor T. Nejat Veziroglu. Published by Elsevier Ltd.
