Enhanced charges separation to improve hydrogen production efficiency by organic piezoelectric film polarization

Using the polarization field by piezoelectric materials was a promising technique to improve the photoinduced charges separation. In this study, PVDF-BaTiO3-Cd0.9Zn0.1S (PVBC) flexible composite films were synthesized via a spin-coating method. The composite films were detailed characterized by XRD, SEM, XPS, DRS and PFM. Based on the experimental results, the polarization field generated by the piezoelectric PVDF and BaTiO3 effectively enhanced...
