Article Abstract:
The insertion of platinum tetrachloride molecules into graphite layers, their reduction behavior, and the formation of platinum metal nanosheets containing hexagonal holes are studied. The sheets had a number of hexagonal holes and edge angles of 120 degree, owing to the limited aggregation of the intercalated platinum chloride molecules to platinum sheets along regular hexagonal nets of carbon atoms between graphite layers.

Article Abstract:
The structures of a series of pristine and Zn(super 2+)-impregnated aluminas are investigated following fluorination with HF, by using both solid-state NMR and X-ray powder diffraction methods. It is demonstrated that the structural chemistry of fluorinated aluminas is dependent on the starting material, the presence of transition-metal cations, and the nature of the fluorinating agent.
