Synthesis and Characterization of a New Organic Photosensitizer and its Application in Photocatalytic H_2 Production by Sensitized Nano-TiO_2 under Visible Light Irradiation
A new triphenylamine derivative organic photosensitizer(PS)with D-.π-A structure,naming(E)-2-cyano-2-((Z)-5-(4-(diphenylamino)benzylidene)-4-phenylthiazol-2(5H)-ylidene)acetic acid(TPAD)had been designed and synthesized using triphenylamine and acetophenone as raw materials,and the structures of target compound TPAD were characterized by1 HNMR,13 CNMR,IR,UV-Vis,XRD and SEM.And then,the target photosensitive catalyst TPAD/Pt(w=0.5%)/TiO_2 was prepared and the H2 production activity of the system composing TP...
