Adsorption of Pd(hfac)2 on mesoporous silica SBA-15 using supercritical CO2 and its role in the performance of Pd–SiO2 catalyst

Preparation of Ordered Mesoporous Alumina Supported‐ZnO/NiO Nanocomposite Using Supercritical Carbon Dioxide Impregnation and Its Photocatalytic Performance

“…In comparison to conventional methods, the supercritical carbon dioxide impregnation technology has significant advantages in preparation of supported nanocomposites. Supercritical carbon dioxide (Tc=304.15 K, Pc=7.38 MPa) possesses low viscosity, low viscosity, high diffusivity relative to liquids and extremely low surface tension . It has been used to synthesize supported catalysts due to these attractive properties.…”

“…Supercritical carbon dioxide (Tc = 304.15 K, Pc = 7.38 MPa) possesses low viscosity, low viscosity, high diffusivity relative to liquids and extremely low surface tension. [9][10][11][12] It has been used to synthesize supported catalysts due to these attractive properties. Therefore, precursors can efficiently penetrate within porous support without damaging its pore structure and morphology since the capillary forces are avoided by supercritical CO 2 impregnation.…”

Preparation of mesoporous SBA‐15/polymer‐copper(II) composites in supercritical CO2 and their multiple applications

“…By contrast, developments on supercritical fluid technology in the field of materials generation, especially in the production of mesoporous materials, are rapidly increasing. During the synthesis of metallic nanostructures, supercritical CO 2 (scCO 2 ) is typically used as the reaction medium in chemical fluid deposition . The supercritical fluid is a good solvent for metal precursors and exhibits high diffusivity and low viscosity, which enable effective infiltration of the metal precursors into mesoscaled templates .…”

Electrochemical performance of fuel cell catalysts prepared by supercritical deposition: Effect of different precursor conversion routes

“…SCD has been shown to be a very powerful technique for the preparation of supported nanoparticles with excellent control of loading, particle size and distribution [18,21]. In SCD, the metal loading on the substrate can be controlled thermodynamically by using the adsorption isotherm of the metal precursor-substrate system [24,[27][28][29][30][31][32]. The maximum loading is also governed by the http://dx.doi.org/10.1016/j.supflu.2014.08.014 0896-8446/© 2014 Elsevier B.V. All rights reserved.…”
