Ru(0001) model catalyst under oxidizing and reducing reaction conditions: In-situ high-pressure surface X-ray diffraction study
Article Abstract:
The oxidation of the Ru(0001) model catalyst under various reaction conditions, starting from a strongly oxidizing environment to reaction conditions typical for CO oxidation were investigated in-situ with surface X-ray diffraction (SXRD) using a high-pressure reaction chamber. The RuO2 films on Ru(0001) were readily reduced by H2 and CO exposures at 415 K, without an induction period.

Catalytic oxidation of ammonia on RuO(sub 2)(110) surfaces: Mechanism and selectivity
Article Abstract:
The selective oxidation of ammonia to either N(sub 2) or NO on RuO(sub 2)(110) single-crystal surfaces was investigated by a combination of vibrational spectroscopy, thermal desorption spectroscopy, and steady-state rate measurements under continuous flow conditions. The results demonstrated that selectivity depended on external parameters for the reaction on Pt surfaces.

Comparison of epoxidation and Baeyer-Villiger reaction pathways for Ti(IV)-H(sub 2)O(sub 2) and Sn(IV)-H(sub 2)O(sub 2)
Article Abstract:
The mechanisms and performance of Ti(IV)-H2O2 and Sn(IV)-H2O2 catalytic oxidation systems with model epoxidation and Baeyer-Villiger reactions are compared. The energetics calculated for the activation of hydrogen peroxide over tin catalysts are similar to the energetics calculated for titanium analogues.
