The entire spectrum of tools in synthetic inorganic chemistry, including high temperature methods, precipitation, solvothermal synthesis, sol-gel chemistry, chemical vapor deposition (CVD), and soft matter techniques adopted in part from organo-metallic chemistry, have been applied to synthesize the active mass of catalysts. Table 4.2.1 summarizes basic techniques. The preparation methods differ whether... 

Organotransition metal oxides or organo 0x0 complexes see Oxo Complex) represent a fast expanding area for early transition metals of groups 4 to 7, due to their relationship with catalytic species formed on the surface of oxides under catalytic conditions. Furthermore, they may also supply a convenient set of volatile starting materials for application in Metal-Organic Chemical Vapor Deposition and related techniques of solid-state and surface chemistry. Most of... 

The synthetic methods which have been used include modem verrions of established methods for metal colloid preparation such as the mild chemical reduction of solutions transition metal salts and complexes, newer methods such as radio-lytic and photochemical reduction, metal atom extrusion from labile organo-metallics, and metal vapor synthesis techniques. While some of these reactions have been in use for many years, others have resulted from research stimulated by the current resurgence in metal colloid chemistry. The list of preparative methods is being extended daily, and as examples of these methods are described below the reader will be made quickly aware that almost any organometallic reaction whose hitherto undesirable side effect is the facile deposition of metallic precipitates is a resource for the metal colloid chemist. The acquisition of new methods is limited only by the ingenuity of the synthetic chemist in turning a previously negative result into a synthetic possibility. Examples of each of these methods will be described below.
