Fiber based structured materials for catalytic applications

Foam/fiber-structured catalysts: non-dip-coating fabrication strategy and applications in heterogeneous catalysis

“…Metal fiber/foam-based supports have attracted everincreasing interest within the last decade [3]. Besides the high voidage and internal-diffusion as typically in ceramic honeycomb catalysts, their unique three-dimensional (3D) network and open structure as well as high thermal conductivity and mechanical strength allow low pressure drop, high mass/heat transfer and especially high contacting efficiency of reactants resulted from the radial mixing ( Fig.…”

Pt-based structured catalysts on metallic supports synthesized by electroless plating deposition for toluene complete oxidation

“…For commercial application, the adhesion strength between active components with substrate supporters is a very important property for the structured catalysts, which directly influence the use and efficiency of catalysts during the operation [13,15,17]. However, the reported structured catalysts directly supported on metallic substrates usually revealed bad adhesion strength, whose weight losses were over 10wt.% via ultrasonic vibration test [31,32].…”

“…Noble metal supported catalysts are well-known highly active catalysts for the oxidation of VOCs [5][6][7][8][9][10]. Particularly, Pt or Pd-based catalysts supported on threedimensional ceramic or metallic structured substrates (such as honeycomb, foam, wire mesh and porous materials) are gaining increasing interest since the resulting structured catalysts offer solutions to problems associated with pelletized catalysts, such as high pressure drop, ambiguous heat and mass transfer characteristics, and handling difficulties [11][12][13][14][15][16]. And the FeCrAl metallic structured substrates hold us more attention for its application as structured catalyst support due to their advantages over ceramic structured substrates such as higher thermal conductivity, greater mechanical shock resistance and easier to machining into various structures [17][18][19].…”

Solvent-free alcohol oxidation using paper-structured catalysts: Flow dynamics and reaction kinetics

“…Beneficial aspects in catalytic applications include the high surface to volume ratio and high void fractions offered by the characteristic fiber-entangled structures [19,20]. Fibrous catalysts are often described as enabling good mass transfer; however, few studies of their fluidic properties have been reported [21,22]. In our previous studies, we developed fibrous catalysts made of inexpensive ceramic fibers using a high-speed and low-cost papermaking technique.…”
