Experimental and theoretical studies on the reaction of H(2) with NiO: role of O vacancies and mechanism for oxide reduction.

Journal of the American Chemical Society

Rodriguez JA, Hanson JC, Frenkel AI, Kim JY, Pérez M.
PMID: 11782187
J Am Chem Soc. 2002 Jan 16;124(2):346-54. doi: 10.1021/ja0121080.

Reduction of an oxide in hydrogen is a method frequently employed in the preparation of active catalysts and electronic devices. Synchrotron-based time-resolved X-ray diffraction (XRD), X-ray absorption fine structure (NEXAFS/EXAFS), photoemission, and first-principles density-functional (DF) slab calculations were used...

Spectroelectrochemical studies on the reactivity of butanol isomers on Pt electrodes in perchloric acid medium led to the observation of structural effects that result from the different arrangements of atoms in the organic molecules. The use of differential electrochemical...

Molecular level study of the formation and the spread of MoO3 on Au(111) by scanning tunneling microscopy and X-ray photoelectron spectroscopy.

Journal of the American Chemical Society

Song Z, Cai T, Chang Z, Liu G, Rodriguez JA, Hrbek J.
PMID: 12823029
