The cogelation process, i.e. the co-polymerization of a metal complex with the gel precursors, was used for the synthesis of transition metal-doped resorcinol–formaldehyde gels. The aim of this process is to anchor the metal to the polymer so that

Hydrodechlorination of 1,2-dichloroethane on Pd-Ag alloys was used as a test reaction in order to study mass transfer in carbon xerogel supports. The selected supports were obtained from evaporative drying and pyrolysis of resorcinol-formaldehyde aqu

Resorcinol–formaldehyde gels were produced at 50, 70 and 90 °C and with three different R / C ratios (500, 1000 and 2000). The effect of these variables combined with that of aging time was studied in order to optimize the synthesis conditions. Th

Carbon materials with tailored texture can be obtained from drying and pyrolysis of resorcinol–formaldehyde gels. The pore texture of both dried and pyrolyzed material depends on the drying process. Several more or less expensive methods (supercrit

Porous carbon xerogels synthesized in a previous study were investigated as catalysts supports. The support chosen was a micro-mesoporous carbon xerogel obtained from the pyrolysis of a resorcinol–formaldehyde resin whose synthesis variables were f

This study consists in identifying and testing potential inorganic substitutes to carbon based materials commonly used as adsorbents for the removal of organic pollutants such as dioxins and furans released from Municipal Solid Waste Incinerators (MS

The pore texture of carbon materials obtained from evaporative drying and pyrolysis of resorcinol–formaldehyde aqueous gels is controlled by the initial pH of the precursors solution. In order to produce transition metal-containing carbons with tai

Despite commonly accepted ideas, evaporative drying does not always completely destroy the pore texture of phenolic gel. This work shows that very porous carbon materials can be synthesized by evaporative drying and pyrolysis of aqueous resorcinol–

Molten salts have been widely used for the electrochemical preparation of lanthanum and uranium metals at high temperature. In this paper we demonstrate the feasibility of a similar process in dimethylformamide (DMF) and in the mixture g-butyrolacton
