摘要:

The passage of paraffins and olefins with six or more carbon atoms over catalytic metals and metal oxides can lead to ring closure, Although this reaction was noticed first by three independent groups of Russian workers [1–3], it gained industrial importance through the work of Grosse and co-workers [4] in making toluene from heptane over alumina-supported metal oxide catalysts.

摘要:

Planar transition aluminas are gaining attention as models for alumina-based catalysts [I] because of their attractiveness for study by modern surface analytical techniques [2], electron optical methods [3], and reflection spectroscopy [4–7]. In this context “planar” means a thin (<10–4 cm) flat oxide layer of uniform thickness. Conventional high surface area aluminas which are used commercially for adsorbents, catalysts, and catalyst supports usually require grinding and /or pressing into disks for characterization by these approaches. This can expose unwanted inner structures or expose the samples to potential contamination by the grinding and pressing tools or uncontrolled atmospheres. In addition, difficulties arise in attempting to study the various stages of alumina development involved with commercial methods since these entail sols, gels, powdered hydroxides, and other inconvenient structures.

摘要:

Recently, interest in catalytic gasification of carbon has expanded rapidly. In consequence of the volume and diversity of this interest, there is a need to collate, summarize, and interpret the available information on the mechanism of gasification catalyst action.

摘要:

In the past decade remarkable progress has been made in the surface science of catalysis. Studies on both small single crystal metal particles on supporting materials and on large (bulk) single crystals point toward a more refined understanding of the fundamental processes underlying catalytic chemistry and, hopefully, toward a rational design of catalytic materials. It seems clear that concepts gleaned from studies on single crystal surfaces will strongly influence the research with supported metal catalysts and ultimately affect the nature of the materials used as practical catalysts.
