The control of porosity at nano scale in resorcinol formaldehyde carbon aerogels
Organic aerogels were synthesized by sol–gel polymerization of resorcinol (R) with formaldehyde (F) catalyzed by sodium carbonate (C) followed by vacuum drying. The influence of the resorcinol/sodium carbonate ratio (R/C) on the porous structure of the resultant aerogels was investigated. The nitrogen adsorption–desorption measurements show that the aerogels possess a well developed porous stru...
متن کاملKraft Lignin Depolymerization in an Ionic Liquid without a Catalyst
In this paper, the depolymerization of lignin was successfully achieved by the thermal treatment of kraft lignin in butyl-1,8-diazabicyclo[5.4.0]undec7-enium chloride ([DBUC4][Cl]) without a catalyst. The thermal treatment experiments were performed in an oven at 150, 200, and 250 °C for 1 h. The changes in kraft lignin structure over the course of depolymerization were characterized by gel per...
متن کاملFabrication of Agar/biopolymer Blend Aerogels in Ionic Liquid and Co-solvent Mixture
In the present study, a biopolymer (cellulose, rice starch or zein protein) was dissolved in the ionic liquid (1-butyl-3methylimidazolium chloride) and co-solvent (dimethyl sulfoxide) mixture (1:1 weight ratio), and then blended with the agar solution, followed by gelation at low temperature. The blends were soaked and shaken in 250 mL distilled water, washed and freeze-dried. The agar/biopolym...
متن کاملPreparation and Characterization of Organic Aerogels from a Lignin - Resorcinol - Formaldehyde Copolymer
Lignin can be used as a cheap natural raw material to prepare organic aerogels based upon gelation and supercritical drying in ethanol. The aerogels were prepared from a mixture of the raw materials with lignin (L), resorcinol (R), and formaldehyde (F), followed by a reaction catalyzed by NaOH(C). The effect of the preparation conditions, such as the LRF concentration, the mass ratio of LR to N...
متن کاملData for the synthesis of resorcinol–formaldehyde aerogels in acidic and basic media
The aim of this research is to synthesise carbon aerogels and to compare the differences in their textural, morphological and chemical properties when synthesised in basic and acidic media, and with two different types of pretreatment carbonization and activation with CO2. Four samples are prepared and characterised using TGA-DTA, SEM, DRX, isotherm determination of N2 adsorption-desorption at ...
