Barium strontium titanate (Ba x Sr 1 − x TiO 3 , BST) films were prepared by rf magnetron sputtering with the substrate temperature ranging from 25 to 550 °C and were investigated by transmission electron microscopy (TEM) equipped with an energy d

Using tunneling spectroscopy we have studied the preparation and behavior of dispersed rhodium model catalysts supported on alumina. Samples were prepared by vacuum evaporation from Rh metal or Rh 2 O 3 sources onto an oxidized Al film and CO was ads

A consistent picture relating the nature of the surface phases of Pt on g‐Al2O3 with the asymmetric shapes of the infrared profiles of chemisorbed CO is given. Observed quantities are (i) the absorption coefficient of the profile of the CO stretchi

Catalysts of varying concentrations of cobalt oxide on ZrO 2 supports were prepared by impregnation and calcination to 600 °C. In very dilute catalysts the cobalt oxide consists of a two-dimensional dispersed “δ-phase” of as yet undetermined st

The effects of CeO 2 and MoO 3 on the surface interaction in the Pt/γ-Al 2 O 3 system were studied by selective chemisorption of CO on Pt to measure the dispersion, sintering and redispersion of PtO 2 on 3.6% CeO 2 /γ-Al 2 O 3 and 5.3% MoO 3 /γ-Al
