The photocatalyst (DPPBI/Pt/TiO2)was prepared using N,N’-di(4-pyridyl)-3,4,9,10-perylene tetracarboxylic acid bisimide (DPPBI) sensitized Pt/TiO2 and characterized by infrared spectroscopy(IR), UV-Vis diffuse reflectance spectroscopy (UV-Vis DRS), scanning electron microscopy(SEM), X-ray photoelectron spectroscopy(XPS), and X-ray diffraction (XRD). The results of characterizationshowedthat the crystal form of TiO2was anatase, Ptwas highly dispersed on the surface of TiO2 and DPPBI was adsorbed on the surface of Pt/TiO2 in DPPBI/Pt/TiO2. Hydrogen production from water splitting using photocatalyst (DPPBI/Pt/TiO2) was studied. It has been found that the rate of hydrogen evolution reaches 6.69 滋 mol·h-1·g-1 under visible light irradiation for 8 h with 300 W Xe-lamp cold light source when 250 mL reactive liquid contains 0.8 g·L-1 photocatalyst (0.1%DPPBI/0.4%Pt/TiO2) and 0.2 mol·L-1 KI.
