The adsorption interaction between molecular hydrogen and atoms forming the lattice of AlPO-5 zeolite is studied. The potential of intramolecular interaction is calculated by summing the potentials of individual pairwise H 2 -O(Al, P) interactions in a fragment of the zeolite structure with a ...
zeolite framework structure or in clusters of charge balancing cations. Also, there are reverse processes in which electron rich sites of the zeolites can donate an electron to a photo excited molecule. The method of encapsulation of TiO

The isomorphic substitution by zinc showed the best results in terms of the percentage of the incorporated metal, while the substitution by cobalt presented the lowest rate of incorporation in the framework of the zeolite CoAPO-5. The adsorption of water in the vapor state...
This work deals with the preparation of MAPO-5 zeolite by a hydrothermal method. In order to study the adsorption properties of this zeolite several transition metals (Fe, Co, Ni, Mn and Zn) were incorporated by a direct route. The obtained zeolites were characterized by various physico-...

Pd catalystMetal-support interactionAnthraquinoneDispersionHighly dispersed Pd/AlPO-5 catalyst was prepared and tested in the hydrogenation of 2-ethylanthraquinone. Characterization results suggested that the abundant surface P-OH groups of AlPO-5 zeolite substituted NH3ligands of [Pd(NH3)4]2+precursor ...
