| Summary: | 碩士 === 靜宜大學 === 應用化學系 === 101 === The purpose of this research is chiefly about prepare Pd-Pt/N-TiO2 photocatalysis. The experiment is prepared N-TiO2 photocatalysis and use the impregnation method the surface of Pd-Pt photocatalysis. The excitation wavelength to made a series of TiO2 is 380 nm could be shifted to long wavelength.The all experiment system light region which use a 400 W mercury arc lamp cutoff filter that filter out all the wave under 400 nm. In this reaction, add 250 ml 10 vol% methanol solution as sacrificial reagent.
The results show sacrificial reagent the useful application of hydrogen production. The TiO2 is doped which assay the physical function with XRD、TEM、EDX、UV-Vis、BET 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、0.1 wt% Pd-0.05 wt% Pt/N- TiO2, we could get the best hydrogen production rate obtained through water splitting is about 1019 μmol/1h．1g.
