摘要

本研究展示了使用添加氧化石墨烯的钛光催化剂P25 -氧化石墨烯(Degussa P25 with Graphene Oxide),在不同的氧化石墨烯重量比例(0.5,2和4%)下光催化水裂解制氢(H2)的结果。通过DRX、FTIR、Raman、UV-vis和SEM对材料进行了表征。XRD表征检测到TiO2和GO的物相为锐钛矿和金红石,拉曼光谱证实了这一点。在FTIR光谱中,观察到浸渍P25-GO光催化剂中存在氧化石墨烯和还原氧化石墨烯。紫外可见光谱(漫反射)和Kubelka-Munk理论观察到,氧化石墨烯与TiO2的掺入导致Eg在2.96-3.14 eV的区间内向可见光区偏移。在室温下,用岛津GC-2014色谱仪监测6小时的制氢反应。其中P25-GO 2%光催化剂用量为45,006 μmol、P25-GO 4%用量为21,922 μmol时产氢量最大;

Photo-catalytic water splitting : TiO2 – GO for water splitting
This work shows results obtained in photocatalytic water splitting for production of hydrogen (H2) using Graphene Oxide – additioned Titanium photocatalysts, P25–GO (Degussa P25 with Graphene Oxide) with different proportion in weight of GO (0.5, 2 and 4 %). Materials were characterized by DRX, FTIR, Raman, UV-vis and SEM. The phases detected by XRD characterization are anatase and rutile of TiO2 and GO, this is confirmed by means of Raman spectroscopy. In FTIR spectra, presence of GO and reduced (rGO) in the impregnated P25–GO photocatalysts was observed. UV-Vis spectroscopy (diffuse reflectance) and applying the Kubelka–Munk theory, it was observed that incorporation of GO to TiO2 lead to a shifted of the Eg towards visible region in the interval of 2.96–3.14 eV. The reaction for H2 production was monitored during 6 hours of reaction at room temperature and by means of a Shimadzu GC-2014 chromatograph. Where maximum production of H2 was obtained with the P25–GO 2% photocatalyst with 45,006 μmol and secondly P25–GO 4% with 21,922 μmol, using a UV vapor lamp of Hg.
