چکیده
Hybrid polyoxometalate–porphyrin copolymeric films can be obtained by the electro-oxidation of 5,15-ditolyl porphyrin (H 2 T P) and zinc-β-octaethylporphyrin (ZnOEP) in presence Lindqvist-type polyoxovanadates TBA [V 6 O 13 {(OCH ) 3 CNHCO(4-C 5 H 4 N)} ] (Py-V -Py). The photocatalytic properties these have been studied for reduction silver platinum ions. In hybrid materials, porphyrins excited visible light then play role photosensitizers able to give electrons catalysts. Des copolymères hybrides polyoxométalate–porphyrine peuvent être obtenus par électrooxydation de la porphyrine et du zinc-β-octaéthylporphyrine en présence des type Lindqvist Les propriétés photocatalytiques ces ont été étudiées pour réduction ions argent platine. Dans matériaux hybrides, les porphyrines excitées lumière jouer alors le rôle photosensibilisateurs capables donner électrons aux catalyseurs polyoxovanadates.

Photocatalytic reactivity tuning by heterometal and addenda metal variation in Lindqvist polyoxometalates.
A systematic study into the effects of metal substitution on the visible-light photocatalytic activity of prototype metal oxide cluster anions is presented. Four isostructural Lindqvist clusters [V(x)M(6-x)O19]((2+x)-) (M = W, Mo, x = 1, 2) with photooxidative activity in the visible range are reported. It is shown that the photooxidative performance correlates with the number of vanadium atoms...

Metal substitution in a Lindqvist polyoxometalate leads to improved photocatalytic performance.
The photochemical properties of homo- and heterometallic molybdate-based Lindqvist polyoxometalate clusters are investigated in a comparative study and it is shown that vanadium substitution can be used as a facile synthetic tool to optimize the visible light absorption and photocatalytic activity of the cluster. The mono-vanadium substituted unit, [VMo(5)O(19)](3-) shows light absorption up to...
متن کاملMETALS RECOVERY FROM SPENT Zn-MnO2 BATTERIES BY HYDROMETALLURGY
A hydrometallurgical process for recycling spent Zn-MnO2 batteries was developed, involving leaching with sulfuric acid, purification by precipitation and metals separation for further recovery. Leaching of zinc oxide was easily attained while for manganese oxide was rather difficult depending on temperature and acid concentration. At 90oC and with the liquid/solid ratio of 20 L/kg, more than 9...
