The external surface of a hydrothermally treated H-ZSM-5 zeolite was studied with XPS and x-ray Auger electron spectroscopy. It was established that Al removed from tetrahedral framework positions migrated into the outermost layers and produced an Al enrichment. In order to get information on the ac

operations were carried out under inert gas. Yield: 0.32 g P,Se, 3 (5.62% of the roretical).
Photoinduced electron transfer to yield charged-separated states is the most fundamental energy conversion process of the photovoltaic effect, exciton storage in semiconductors, and photosynthesis. Ionization of organic molecules on heterogeneous catalysts is predicted to become an exciting area of
