Abstract:
In this projekt, nanophotocatalysts containing metal oxides and oxy-acids based on the nanoporous materials were synthesized. The photocatalytic properties of the prepared samples were evaluated by the photodegradation of day moleculs in photocatalytic systems. The catalytic results revealed that Ag3VO4/Cu-MOF/rGO exhibits noticeably an improvement in both efficiency and rate of AB92 photodegradation in comparison with the pure Ag3VO4. Using different scanning mechanisms for the catalytic properties of the synthesized nanocomposites, it was clearly demonstrated that the anionic superoxide plays a decisive role. Reduction of 4-NP in the presence of NaBH4 was also used to investigate catalytic properties of Cu2O/ Cu-MOF/rGO nanocomposite The mechanism and kinetics of the reduction reaction, depending on the structure of the catalysts used, showed that Cu2O and Cu-MOF adsorbed the molecules involved in the reaction, and rGO transferred electrons between Cu2O and Cu-MOF
