Catalysis homo-/heterogeneous

Homogenous (Homo) Heterogeneous (Het) Biocatalytic (Bio) Phase Transfer Catalysis (PTC). 

There are significant challenges for catalysis to realize these objectives, as detailed in this chapter. There is the need for better integration between bio-, homo- and heterogeneous catalysis, and to foster cross-fertilization between these and contiguous areas (reaction engineering, membrane, etc.). New tools for the synthesis and understanding of these catalysts are need to be developed. 

Research tools and fundamental understanding New catalyst design for effective integration of bio-, homo- and heterogeneous catalysis New approaches to realize one-pot complex multistep reactions Understanding catalytic processes at the interface in nanocomposites New routes for nano-design of complex catalysis, hybrid catalytic materials and reactive thin films New preparation methods to synthesize tailored catalytic surfaces New theoretical and computational predictive tools for catalysis and catalytic reaction engineering...

Metathesis catalysts may be either homo- or heterogeneous. Although complexes of Ru, Mo, and W seem to show the most activity, metathesis may be catalyzed in some instances by Ti and Ta species. Heterogeneous substances, such as WOj/silica or Mo03 and Mo(CO)6 supported on alumina, catalyze the Triolefin Process and others performed on an industrial scale. Mechanistic studies of the type described in the previous section were essentially impossible to do with heterogeneous catalysts because the nature of these catalysts was so ill defined. Further discussion of the mechanism of metathesis under heterogeneous catalysis is beyond the scope of this textbook. 

However it must be borne in mind that many examples of more complex surfaces are known. Clays and zeolites show huge internal surface area, with a variety of layers and pore sizes. The whole field of heterogeneous catalysis depends on nano-structured surfaces of massive area, which certainly can not be thought of as planar. Grain boundaries may be thought of as internal surfaces or homo-interfaces [27] and are perhaps similar to the solid-liquid interface during melting.
