| Summary: | 碩士 === 靜宜大學 === 應用化學系 === 99 === The purpose of this research is chiefly about prepare TiO2 photocatalysis which can work under visible light. The study is prepared a series of N-TiO2 photocatalysis and impregnate the surface of N-TiO2 with platinum cation. The excitation wavelength of TiO2 is 380 nm could be shifted to long wavelength and improve the yield of hydrogen production.
The study focus the energy conversion efficiency in the visible
light region which use a 400 W mercury arc lamp combined with a 400 nm cutoff filter that filter out all the wave under 400 nm. 0.5 g potocatalysis perform water splitting reaction in 250 ml 10 vol% methanol solution in Pyrex glass reactor.
The results show sacrificial reagent the useful application of hydrogen production. The TiO2 is doped which assay the physical function with EPR、UV-Vis and other apparatus to prove the TiO2 be changed. Many factors is tried out and get a best condition to hydrogen production. When system condition for N/Ti= 10、0.05 wt% Pt/N- TiO2, we could get the best hydrogen production rate obtained through water splitting is about 772 μmol/h．g.
