CO chemisorption and hydrogenation of surface carbon species formed after CO/He reaction on Rh/MgO: A transient kinetic study using FTIR and mass spectroscopy
Efstathiou, Angelos M.; Chafik, T.; Bianchi, D.; Bennett, C. O. (1994)The chemisorption of CO and hydrogenation of surface adsorbed carbon species formed after reaction of CO/He with Rh/MgO catalyst in the range 300-573 K were studied by transient methods employing both FTIR and mass ...

Hydrogen Surface Concentration Effect on the Temperature-Programmed Hydrogenation of Adsorbed Carbonaceous Species on an Iron/Alumina Catalyst
Halafi, H.; Borgstedt, E.; Efstathiou, Angelos M.; Suib, S. L.; Bianchi, D. (1993)Temperature-programmed hydrogenation (TPH) of adsorbed carbonaceous species on metallic catalysts is a useful method to measure their numbers and reactivities. In the present paper it is shown that changes in the T.P.H ...

In Situ Determination of Surface Carbon Species Formed on Rh/Al2O3 During CO/H2 Reaction by using Various Transient and Isotopic Methods
Efstathiou, Angelos M.; Chafik, T.; Bianchi, D.; Bennett, C. O. (1993)The evolution of surface species formed during the CO/H2 reaction at 220°C on a 1wt% Rh/Al2O3 catalyst was studied by transient methods using both mass spectrometry and FTIR. There is a very small amount of active carbon, ...

A Transient Kinetic Study of the Co/H2 Reaction on Rh/Al2O3 Using FTIR and Mass Spectroscopy
Efstathiou, Angelos M.; Chafik, T.; Bianchi, D.; Bennett, C. O. (1994)The evolution of surface species (their chemical composition and surface coverage) formed during the CO/H2 reaction at 220°C on 1 wt% Rh/Al2O3 catalyst was studied by transient isotopic and various hydrogen titration ...
