“…In this way, the porous texture of the carbonaceous component can be combined with the basic properties of the oxides. Zr-containing carbon aerogels obtained by copolymerization of organic and inorganic (zirconium(IV)-propoxide) precursors display a more uniform distribution of the metal in the carbon matrix than supported catalysts prepared by other methods [15]. Addition of Ce 3þ and Zr 4þ to the resorcinol-formaldehyde solution enhances the means of controlling the porosity in the micropore region.…”

“…By using this sol-gel method, several alkaline and transition metal ions, can be well dispersed in the RF gels and its carbonized derivatives during the synthesis process [1,[7][8][9]. The incorporation of metal ions in the RF gels or its carbonized derivatives leads to a hybrid material with potential applications as catalyst [7], supercapacitor [10], and lithium-ion battery anode [11].…”

Synthesis and characterization of TiO 2 -carbon nanocomposites with both micro-and mesopore size distributions, Materials Letters (2010Letters ( ), doi: 10.1016Letters ( /j.matlet.2010 This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. Abstract: TiO2-carbon nanocomposites were synthesized by simply mixing a TiO2 sol with a semi-cured resorcinol and formaldehyde gel, followed by drying and pyrolysis at 1000 o C in an inert atmosphere. ACCEPTED MANUSCRIPTFor comparison, the pure resorcinol and formaldehyde gel and the pure TiO2 gol were also prepared, dried and pyrolysed in same conditions, respectively. The composites with a low TiO2 content had the similar pore size distribution (PSD) and crystallographic structure to that of the blank sample (i.e., micropore size distribution), However the presence of high content TiO2 in the composites effectively resulted in an increase in mesoporosity and a crystallographic structure of dominant rutile TiO2 in the TiO2-carbon nanocomposite.

“…In the post-impregnation technique the added metal also affects the pore structure through pore blocking [43]. In addition to doping with Na, Mg, K [44], Ti [45,46], Cr [47], Fe, Co, Ni [42], Cu [40,42,48,49], Zr [50], Ru [51], Pd, Ag [34], W [47] and Pt [34], studies on Mo-doped carbon aerogels have also been reported [47].…”

High surface area carbon aerogels with increasing molybdenum content were obtained by carbonization of resorcinol-formaldehyde polymer aerogels after incipient wetness impregnation (IWI). The Mo(VI) form of the impregnant was converted into different molybdenum species during the heat treatment, resulting in samples with substantially different surface and bulk compositions. The samples were tested in the hydroconversion reaction of acetic acid, a model biomass. The reaction pathways and the product distribution were governed by the accessibility of the carbon surface as well as by the amount and form of Mo. The highest selectivity for ethanol was 16 %, when 85 % of the acetic acid was converted. Post-catalyst analysis of the aerogels revealed that their morphology and chemistry changed substantially during the redox processes.The products of each of the three potential pathways (hydrogenolysis, ketonization and consecutive reduction) oxidized the surface even in the reductive hydrogen flow.
