We report an anomalous photoinduced reconstructing and dark self-healing process on Bi2O2S nanoplates by monitoring the time profile of open-circuit potential (OCP). When the light was switched on and off on the nanoplates, we observed pronounced and repeatable decrement-recovery cycles of the OCP signal, which are inexplicable by a rapid electron-hole separation-recombination process only as in a conventional semiconductor. It is proposed that upon irradiation, accumulation of photogenerated holes at the electrode surface caused oxi
