Chemistry, Physics and Technology of Surface| Zusammenfassung: | Ammonium phosphoromolybdate has been embedded into silica structure via sol-gel synthesis and deposition on the surface of oxide supports during mechanochemical treatment. Prepared compositions have been studied by XRD, DTA-TG, FTIR and UV-Vis spectroscopy, nitrogen adsorption. Ammonium phosphoromolybdate retains Keggin structure after embedding into oxide matrix. Samples synthesized through sol-gel method possess micro-mesoporous structure while those mechanoactivated have macro-mesoporous one. All the compositions exhibit higher photocatalytic activity as compared with that of bulk APM in the process of safranin degradation in aqueous medium. |
