Photogenerated charge separation at BiVO4 photoanodes enhanced by a Ag-modified porphyrin polymer skeleton

Porphyrin-phosphazene was modified with Ag NPs on BiVO 4 to fabricate a photoanode. The photocurrent was three times improved due to the synergistic effect. This study provides insight into the charge transfer kinetics of the integrated photoanode by SPECM and IMPS.
