In the first part of this thesis, the reaction of generating hydrogen by photocatalysis on the P lamp TIOZ using the pollutant ethanolamine homologue as the electron donor was studied. The results show that the three ethanolamines can significantly improve the efficiency of photocatalytic hydrogen release, and the pollutants are also well degraded. The effects of reaction time, initial concentration, and pH on photocatalytic hydrogen evolution and degradation of pollutants were studied. Hydrogen production and pollutant degradation are best when they are weakly alkaline (pH around 8-9).
