Aligned aluminophosphate molecular sieves crystallized on floating anodized alutnina by hydrothermal microwave heating

Thin films of aligned zeolite crystals can significantly improve the quality of advanced materials prepared using zeolites as a nanostructured host. A membrane of vertically aligned aluminophosphate molecular sieves is prepared on floating anodized alumina using microwave heating. The Figure shows the first step in the proposed synthetic scheme—preformed nuclei penetrate the cylindrical nanochannels of the alumina substrate.
