Nitrogen-incorporated SAPO-11 molecular sieve: Synthesis, characterization, and properties

Article Abstract:

Nitrogen-incorporated SAPO-11 molecular sieves are synthesized by a secondary synthesis technique at low nitridation temperature (400 degree C) with a starting material of SAPO-11 zeolite doped with two wt % Ru. It was found that nitrogen-containing species had incorporated into framework of SAPO-11 zeolite, in which some N atoms directly bonded to Al and P atoms and formed AlN4, AlN2O2, and PN4 groups.

Characterization of ruthenium oxide nanostructure as a cocatalyst with (Ga(sub 1-x)Zn(sub x))(N(sub 1-x)O(sub x)) for photocatalytic overall water splitting

Article Abstract:

The formation and structural characteristics of Ru species applied as a cocatalyst on (Ga(sub 1-x)Zn(sub x))(N(sub 1-x)O(sub x)) were examined by scanning electron microscopy, X-ray photoelectron spectroscopy and X-ray absorption spectroscopy. Calcination was shown to cause the decomposition of initial Ru3(CO)12 on the (Ga(sub 1-x)Zn(sub x))(N(sub 1-x)O(sub x)) surface to form Ru(IV) species.

Nonadiabatic, short-range, intramolecular electron transfer from ruthenium (II) to cobalt (III) complexes

Article Abstract:

The activation parameters presented for intramolecular electron-transfer between ruthenium (II) and cobalt (III) complexes for the thermodynamic contribution of the entropy change for the reaction to the entropy of activation are verified.
