Studies on the Hydrogen Generation by Photocatalyst TiO_2/Zeolite Decomposed Water

摘要

In order to improve the efficiency of hydrogen generation by photocatalytic decomposes water, the different nature of zeolite is added to photocatalytic TiO_2. Added adsorbent to alcohol solution what containing titanium dioxide, t inspects the effects of the add ratio and properties of adsorbent zeolite and the concentration of alcohol solutions by UV light irradiation. The results show that the optimal concentration of alcohol solution is 30vol%, the best multiplication effects of methanol, ethanol and 1 - propanol aqueous solution were about 8 times, 5 times and 2.5 times. The hydrogen production of alcohol solution were mainly under the influence of surface properties of the adsorbent.
