A review; prepn. of carbon-supported noble metal catalysts (Me/C) is usually based on supporting metal precursors on carbon followed by their transformation into the metal particles. Design of an appropriate catalyst implies an optimal selection of both the support and the method of synthesis of the active component, which requires understanding the following issues: 1. Which physicochem. properties of the support det. its interaction with the metal particles. 2. How do the initial metal compds. interact with the carbon surface. 3. What are the state of the supported precursors and the manner of their fixation on the support. 4. What are regularities of the transformations of these precursors to the metal particles during calcining and redn. steps. Knowledge in the field of prepn. of carbon-supported metal catalysts is expanded as exptl. data are collected and physicochem. techniques for studying catalysts are developed, but it remains insufficient. Whereas development of catalytic compns., even though based on some general empirical approaches is still a matter of skill, the answers to the above-stated questions are often treated as secrets ("know-how") of the catalyst prepn. This is, evidently, the reason for the availability of only fragmentary and sometimes contradictory information regarding these aspects of synthesis of Me/C. In this connection the authors of this chapter see their goal not only as providing a survey of the published data on the problem of the catalyst prepn. but also as creating model concepts to consolidate these data and to account for some existing contradictions.
