Abstract

The aim of this work is to investigate the hydrogen generation from water using H2S as a reducer in the hydrothermal reactions at the mild conditions. The effects of reaction temperature, reaction time and initial pH values of reaction solution on the yields of hydrogen from water were studied. The experiment results showed that hydrogen could be generated from water when the reaction temperature was beyond 200 °C. Moreover, the hydrogen production strongly depended on the initial pH values of the solution. Under strong alkaline conditions the hydrogen production from water was much higher than that under acidity or weak alkaline conditions. The possible mechanism of hydrogen production was discussed.
