Аннотация:The photocatalytic coatings based on the solvothermally-derived submicron particles of layered MoO3, V2O5, and WO3 with the islet TiO2 shell demonstrate excellent photoenergy storage ability accumulating the photoproduced charge, as evidenced by EPR measurements, via generation of hydrogen bronzes and Ti3+ states, whichexhibit gradual oxidation in air conditions yielding peroxide.This continuous production of long-lived oxidation agent imparts high pathophysiological activity to the pre-exposed photocatalysts which retains for unprecedentedly long time (up to 10-12 h).
