Binary alloy surface compositions from bulk alloy thermodynamic data

Frank L. Williams, +1 more
- 01 Oct 1974 - 
TL;DR: In this paper, the surface composition of binary alloys is determined by minimizing alloy surface free energy with respect to atom exchange between the surface and the bulk, using a pairwise bound model of the solid with a broken bond surface.

Surface Composition and Selectivity of Alloy Catalysts

W.M.H. Sachtler, +1 more
- 01 Jan 1977 - 
TL;DR: In this paper, the authors show that the surface composition of macroscopic alloys often differs from the bulk composition, and the secondary ensemble effect that ascribes changes in heat of chemisorption of multiply bonded atoms to a decrease in the coordination of these atoms to the surface metal atoms.

Predictions for surface segregation in intermetallic alloys

James R. Chelikowsky
- 02 Apr 1984 - 
TL;DR: In this paper, Miedema has proposed an empirical method for predicting surface segregation in intermetallic alloys and presented an overview of his predictions for all transition metal binary combinations.

Surface composition and chemistry of supported platinum-iron alloys

C.H. Bartholomew, +1 more
- 01 May 1973 - 
TL;DR: Mossbauer spectroscopy and chemisorption data involving H2 and O2 have been used in a complementary manner to determine the surface composition of carbon-supported platinum-iron alloys.

Preparation of highly dispersed catalytic metals: Platinum supported on silica gel

H.A. Benesi, +2 more
- 01 Apr 1968 - 
TL;DR: In this paper, supported platinum consisting of 15-A crystallites has been prepared by reduction of platinum ammine ions adsorbed on the surface of silica gel, which has been carried out by hydrogen chemisorption, X-ray diffraction, and electron microscope techniques.

Hydrogen chemisorption and surface composition of silica-supported platinum-copper alloys

James H. Anderson, +2 more
- 01 Mar 1970 - 
TL;DR: In this article, the surface composition of the alloy crystallites depends upon crystallite size: the larger the crystallite, the more the surface is enriched with copper, while small crystallites (diameter) are enriched with silica.
