摘要
A PMMA (polymethly methacrylate) oligomer coating photoanode sensitized with the Ru(bpy)3 phosphoric acid derivative 1 as photosensitizer and complex 2 as water oxidation catalyst was assembled for light driven water splitting. A simple and effective method was optimized by immersing the sensitized photoanode into the DCM solution dissolving 2 wt% PMMA for 15 s. With the decorated photoanode as working electrode, the DS-PEC displayed much better long-term stability, the photocurrent density of which was found to be 0.57 mA/cm(2) after 200 s sustaining light illumination and is four times as high as the undecorated one (0.15 mA/cm(2)).
