Since much of the impetus for our STM studies stems from earlier spectroscopic investigations of alkali metals and alkali metal-modified surfaces,6 we consider first what was learnt from the caesiated Cu(l 10) surface concerning the role of different oxygen states, transient and final states, in the oxidation of carbon monoxide, and then examine how structural information from STM can relate to the chemical reactivity of the modified Cu(110) surface. 

For over 15 years we have conducted research utilizing metal atoms in low temperature spectroscopic and synthetic studies at Rice University.8 Our synthetic work was started in the late 1960s with the work of Krishnan, on lithium atom reactions with carbon monoxide, extended by Meier- in his studies of lithium atom reactions with water and ammonia and expanded over the next several years to include metal atom interactions with HF, H2O, H3N, H4C, and their hundreds of organic analogs—RF, R2O, ROH, R3N,. . . H3N, R4C, R3CH, etc. A most exciting aspect of... 

Vibrational Spectroscopic Studies of Adsorbate Competition During Carbon Monoxide Adsorption on Platinum Electrodes... 

It is essential to understand the mechanisms of methanol oxidation including the adsorbate formation and removal. To this purpose, the electrochemical oxidation of adsorbed carbon monoxide (COad) and methanol was studied using electrochemical and two spectroscopic... 

Carbon monoxide partial pressures exceed ca. 70 bar (5). Spectroscopic studies of typical Ru3(C0)i2 Co2(C0)8-l2/ Bu4PBr catalyst solutions have served to aid considerably in unraveling the differing roles of the ruthenium, cobalt and iodide-containing catalyst components in these syntheses. A typical solution spectrum in the metal-carbonyl region (5) shows the presence of significant concentration s of both [Ru(CO)3I3] (2108 and 2036... 

The reaction of 02 with cytochrome c oxidase to form the oxygenated species A (Fig. 18-11) is very rapid, occurring with apparent lifetime T (Eq. 9-5) of -8-10 is.139 Study of such rapid reactions has depended upon a flow-flash technique developed by Greenwood and Gibson.136/140/141 Fully reduced cytochrome oxidase is allowed to react with carbon monoxide, which binds to the iron in cytochrome a3 just as does 02. In fact, it was the spectroscopic observation that only half of the... 

Carbon monoxide chemisorption on Ni 7 9 11 represents an interesting case with which to check these concepts since comparable studies have been performed on Ni 001 and Ni lll and since a number of other experimental methods have been applied to this system. Electron energy loss spectroscopic (EELS) studies performed at 150 K suggest that the initial adsorption occurs in threefold and twofold bridge sites along the step edge. Beyond this point, the CO molecules begin to occupy terrace sites. (12)...
