The immobilization of peroxidases can be classified in agreement with the support used for immobilization. In this way, three main types can be mentioned on organic, inorganic, and hybrid supports. Each of them displays their own characteristics that make them catalytically attractive and potentially applicable. Next, some examples and strategies are described. Additionally, peroxidases have been immobilized for their use in biosensors development with applications in diagnosis or electronics. These interesting and novel applications are covered in Chap. 6. 

There are some excellent review articles on different aspects of mesostructured materials, such as synthesis, properties, and applications. " Extensive research effort has been devoted to the exploitation of new phases (lamellar, cubic, hexagonal structures), expansion of the pore sizes (about 2-50 nm are accessible), and variable framework compositions (from pure silica, through mixed metal oxides to purely metal oxide-based frameworks, and inorganic-organic hybrid mesostructures). Another research focus is on the formation of mesostructured materials in other morphologies than powders, e.g. monolithic materials and films, which are required for a variety of applications including, but not limited to, sensors (based on piezoelectric mass balances or surface acoustic wave devices), catalyst supports, (size- and shape-selective) filtration membranes or (opto)electronic devices. The current article is focused... 

In a subsequent report, the Ru precatalyst was immobilized on three different inorganic/organic hybrid sihca supports (1) amine-functionalized (Ru-N/SiO ), (2) phosphine functionalized (Ru-P/SiOj), and (3) thiol functionalized (Ru-S/SiO ) [50]. For levulinic acid hydrogenation to GVL, the performance of the catalysts decreases in the order of Ru-P/SiO > Ru-S/SiO > Ru-N/SiO. When compared to a Ru/C catalyst, the Ru/C exhibits a much higher turnover frequency (10 times greater than Ru-P/SiOj) but has an extremely low yield ( 7% after 12h). This is attributed to the poor selectivity of Ru/C to decompose formic acid to and CO. Furthermore, the Ru-P/SiOj catalyst was used in eight consecutive experiments without noticeable loss of selectivity or yield of GVL [50],...

One such organic-inorganic hybrid support has been synthesized by covalently anchoring a N-octyldihydroimidazolium cation fragment onto Si02 (denoted as... 

In this chapter, pressure driven processes involving porous inorganic or hybrid membranes are particularly examined. As recently shown by Bhave [1], differences with traditional organic elements mainly result from the structure and intrinsic properties of materials, either regarding flow (with ceramic membranes, the transport occiu-s through the intergranular spaces within the top layer, porous sublayers and support, while across polymeric barriers it develops...
