Electronic, structural, and reactive properties of ultrathin aluminum oxide films on Pt(111)

Article Abstract:

The electronic, structural and reactive behavior of alumina films grown on Pt(111) as a function of thickness and oxidation temperature was investigated. Results showed that submonolayer Al films undergo complete oxidation to Al2O3 at 300 K and form a strained crystalline film of gamma-alumina at 1100 K annealing. The Al2O3 films on Pt(111) were also found to increase the coverage and stability of SO4 generated by SO2 chemisorption.

Direct observation of extremely low temperature catalytic dehydrochlorination of 1,1,1-trichloroethane over platinum

Article Abstract:

An attempt is made to report the efficacy of a Pt{111} model catalyst for the direct, low-temperature catalytic dehydrochlorination of 1,1,1-trichloroethane and identify deactivation processes. Atomic chlorine liberated during surface dehydrochlorination undergoes efficient reaction with surface hydrogen, resulting in the evolution of gaseous HCL and small amounts of ethane, presumably through ethylidyne hydrogenation.

Sulfate-enhanced catalytic destruction of 1,1,1-Trichlorethane over Pt(111)

Article Abstract:

The catalytic destruction of 1,1,1-trichloroethane (TCA) over model sulfated Pt(1 1 1) surfaces are investigated by fast X-ray phoelectron spectroscopy and mass spectrometry. TCA absorbs molecularly over SO4 precovered Pt(1 1 1) at 100 K, with a saturation coverage of 0.4 monolayer (ML) comparable to that on the bare surface.
