The research objectives of the study are to manufacture nano-TiO2 with doping Fe3+, Ce3+ and La3+ adopting impregnation method, examine the effects of the preparing condition on catalyst performance, and explore the influence of the adding account of metal ions and different ion-combinations on the photocatalytic activity of modified nano-TiO2. The experiment results support the following three conclusions...
Under various experimental conditions, the paper, taking Al2O3 as modified materials, conducts a study on the catalysis performance of magnetic photochemical catalyzing materials as well as a preliminary analysis on its reaction kinetics. The result indicates four conclusions as following. Firstly, the original concentration of the degraded solution imposes significant influence on photochemical catalysis...
Aimed at the problem solving of difficult reclaiming nanometer TiO2, the paper conducts a study on magnetic recovering by a series of experiments. Firstly, taking methylene blue as the object, the test compares the photocatalytic performance between self-manufactured TiO2 and commercial TiO2 after 160 minutes photocatalytic degradation. The results show that their degradation rates are 94% and 99%...
The paper produces Nano-TiO2 doped with Fe3+, Ce3+, Cu2+, Ce3+ and La3+ using sol-gel method, examines the effects of their preparation condition on catalyst performance, and then explores the influence of the adding amount of metal ions and different ions combinations on photocatalytic activity of modified Nano-TiO2. The result indicates the optimum condition for preparing doped Nano-TiO2 adopting...
