Preparation, characterization, and catalytic performance of bismuth-aluminum binary-oxide layers and clusters on an Al2O3 surface
Article Abstract:
Bismuth oxide on AI2O3 was prepared using Bi(OEt)3 as a precursor and changing the Bi loading systematically and characterized the obtained samples by extended X-ray absorption fine structure (EXAFS) and X-ray photoelectron spectroscopy (XPS). Bismuth-aluminum (rich) binary oxide layers below 9 wt % Bi loading and bismuth (rich) - aluminum clusters above 9 wt % Bi loading was formed at the Al2O3 surface.

Effective deposition potential induced size-dependent orientation growth of Bi-Sb alloy nanowire arrays
Article Abstract:
Single-crystalline and highly preferentially oriented [Bi.sub.1-x][Sb.sub.x] alloy nanowire arrays are prepared into porous anodic alumina membrane by pulsed electrodeposition. Results reveal that the effective deposition potential controls the orientation and diameter of the [Bi.sub.1-x][Sb.sub.x] nanowire.

Structure of MnOx/Al2O3 catalyst: A study using EXAFS, in situ laser Raman spectroscopy and ab initio calculations
Article Abstract:
The structure of a MnOx/Al2O3 catalyst used for ozone decomposition is evaluated using extended X-ray absorption fine structure (EXAFS) and in situ Raman spectroscopy. EXAFS results show that the manganese center is surrounded by four or five oxygen atoms with Mn-O distance of 0.21 nm.
