FTIR and XPS signatures were obtained for various oxidation temperatures and compared with those known from the literature about calcination of Al 2 O 3 precursors. The aim of this work is to evaluate the use of IR spectroscopy and XPS analysis to probe the structural varieties of Al 2 O 3.

FTIR results show that Al2O3 nanofibers are able to dissociate Li⁺ ions from contact ion pairs. XRD analysis demonstrates that the nanofibers can reduce the crystallinity of GPEs.

Aluminium oxide (Al 2 O 3) is from our laboratory.

2013年4月1日 · This work involved preparation and characterization of new catalysts (Ir/Al 2 O 3, Ir–Ru/Al 2 O 3, and Ru/Al 2 O 3), as well as catalytic tests of hydrazine decomposition in a 5 N satellite thruster. Ru is approximately six times cheaper than Ir, being able to partially or completely substitute this metal in short duration missions, in which ...

2002年12月21日 · In this study, transmission FT-IR spectroscopy is used to investigate the adsorption of water on aluminum oxide surfaces, including both single-crystal and particle surfaces. The FT-IR spectra of the (0001) surface of α-Al 2 O 3 single crystals at 296 K in the presence of 0.2 to 20 Torr H 2 O vapor pressure corresponding to 1 to 95% relative ...
