Chemical reactions on solid surfaces using molecular beam techniques. Final rept 1 Jan 72-30 Sep 80

OSTI ID:6652266
Thermal energy molecular beams have been used to study chemical interactions with metal surfaces. Chemisorption of simple molecules such as H/sub 2/, O/sub 2/, CH/sub 4/, C/sub 2/Hx and CO was investigated on single and polycrystalline surfaces of Pt, Ni, Co, and Ag. Kinetic parameters and reaction mechanisms were determined for model catalytic reactions including CO and C/sub 2/H/sub x/ oxidation and methanation from H/sub 2//CO mixtures. Chemical reactions of NO/sub x/ with CO and D/sub 2/ on Pt(111) and other surfaces have been surveyed and the kinetics of NO and O2 chemisorption have been measured. The theory of adsorption/desorption kinetics is reviewed and certain deficiencies identified.
