Surface of metal catalysts

During the development of MRNi, in 1977 (61a, 61b) we proposed an hypothesis about the mechanism of hydrogenation on the surface of metal catalysts (61a, 61b). In 1971-1974 we proposed the name stereo-differentiation, which is the basic principle for the so-called asymmetric reactions (24, 32, 34, 38, 62, 63). These have been the working hypotheses for the development of MRNi.

The presence on the surface of a dispersed metal catalyst of at least three distinct corner sites having different activities is, however, not compatible with the octahedral models of the 3M sites shown in Fig, 3.4 and used in Schemes 3.2 and 3.4 to develop analogies with specific homogeneous catalysts. A more detailed description of these corner atom sites and others present on the surface of metal catalysts is presented in the next chapter in conjunction with a discussion of the surface electronic orbitals of such species.

CFC are produced via epitaxial deposition of carbon on the surface of metal catalyst. The filaments are shaped by graphite basal planes a filament can be imagined as either a pile of truncated cones put one onto another, each inside the next one, or, if flat, as a card pack [6,7]. Generally, a pile of cones with angle a made by the generatrix and the cones axes, varying from 0 to 90 , may be taken as a model of the CFC structure (Fig.2). The main structural parameters of the CFC s...
