“…The co-condensation of such molecules with a network-forming reagent such as tetraethoxysilane (TEOS), Si(OC 2 H 5 ) 4 , results in materials in which the metal is anchored to the SiO 2 matrix. Heinrichs et al [7,8] and Lambert et al [9][10][11] used this cogelation method to synthesize mono-and bimetallic aerogel and xerogel catalysts. By changing the molar ratio between the functionalized amino-alkoxide and TEOS, textural properties such as pore volume, pore size and surface area can be tailored.…”

“…By changing the molar ratio between the functionalized amino-alkoxide and TEOS, textural properties such as pore volume, pore size and surface area can be tailored. Although metal particles are located inside the silica particles, their complete accessibility, via the micropore network, after drying, high temperature calcination and reduction of the gels, has been shown [7][8][9][10][11].…”

“…Lately, the sol-gel process has been used to prepare supported metal catalysts and catalyst supports with high thermal stability, resistance to deactivation and flexibility to control catalyst properties such as particle size, surface area and pore size distribution. Numerous authors have shown the ability to disperse catalytic metals on gels whose texture is finely controlled by the sol-gel route [10]. The intimate mixing at the molecular level of different components obtained at the end of reactions is probably the main reason for using sol-gel methods [11].…”

“…For example, triethoxysilane has been mixed with Pd(OAc) in an aqueous/organic solution to prepare a Pd/SiO catalyst (6), and X(CH ) Si(OEt) , where X"NH , NHCH CH NH or CN has been reacted with several metal compounds including Pd(acac) and Pt(acac) (7). In another study, Pd> [(NH }CH }CH }NH}(CH ) }Si(OCH ] was cogelled with tetraethoxysilane (8). A common feature of these studies was the high dispersion of the "nal catalyst.…”
