Review on methods to deposit catalysts on structured surfaces

Preparation of binary washcoat deposited on cordierite substrate for catalytic applications

“…As a consequence, lower resistance to gas flow and corresponding lower pressure drop are achieved in structured monoliths than those in packed-beds. A simple way to obtain catalyst monolith is to deposit a catalytic layer on the non-catalytic structured substrate [2,3]. Honeycomb cordierite (2MgO-2Al 2 O 3 -5SiO 2 ), is the substrate in common use because of its superior mechanical stability and hydrothermal stability as well as its plasticity.…”

Bimetallic Catalysts Containing Gold and Palladium for Environmentally Important Reactions

“…Two types of impregnation methods can be used, (i) based on the volume of metallic solution with respect to the pore volume of support, namely incipient wetness and (ii) wet impregnation using excess solvent. In the case of incipient wetness, the active component solution volume is equal to the pore volume of the support and in the case of the wet impregnation methodology the volume of solution is much higher than the total pore volume of the support [55]. Temperature of stirring, time of heating, calcination temperature, and the nature of supporting material are some of the crucial conditions that control the characteristics of the final catalyst.…”

Catalytic characteristics of a copper–alumina nanocomposite formed by the mechanochemical route

“…Several possibilities are reported in the literature on the improvement of catalytic properties. Special attention is directed to methods for producing the catalyst considering, among other things, high dispersion on the support and small particle sizes of Cu and also the addition of promoters [14][15][16][17][18][19]. Recently, a detailed review of steam reforming catalysts, also based on copper, was presented by Sá et al [14].…”
