The deposition of a NaA zeolite layer on porous stainless steel substrates was optimized in order to obtain composite membranes for hydrogen separation. The effect of the silica source on NaA zeolite crystallinity and ...

NaA zeolite membranes were synthesized on top of both disk and tubular porous stainless steel substrates by the secondary growth method. The support seed stage was optimized, considering the seed synthesis conditions and ...

Palladium composite membranes on porous stainless steel were prepared by electroless plating. In order to obtain a thin palladium film, an intermediate layer was necessary to modify the pore size of the substrate and form ...

Pt catalysts were prepared by encapsulating the active metal in the NaA zeolite structure. The catalysts were prepared by hydrothermal synthesis using two heating sources, conventional heating through a thermal bath and ...

The degradation of methylene blue dye was evaluated for a series of in situ generated titania resulting from the impregnation of TiCl4 into a series of NaA zeolites, which were synthesized using alternative silicon sources, ...
