Abstract:
Two new carboxyethyltin‐functionalized polyoxometalates (POMs) were successfully obtained and confirmed with physicochemical and spectroscopic methods including X‐ray crystallography. The lowest unoccupied molecular orbitals of both compounds are higher in energy than that of TiO 2 , and the optical band gaps of these compounds are smaller than that of TiO 2 . Grafting them onto a TiO 2 film created two kinds of novel photoanode materials that showed significantly enhanced photovoltaic and photocurrent responses, as well as improved photoelectrooxidation activities for methanol relative to that shown by a single TiO 2 film. Further, P 2 W 15 ‐Co‐SnR produced the largest photocurrent by exploring the photoelectric activities of a series of carboxyethyltin POM derivatives. This work provides new insight into the photoelectrochemical functionalization of POM‐based organic–inorganic hybrids.
