Microporous and mesoporous carbon xerogel having a characteristic mesopore size and precursors thereof and also a process for producing these and their use |
| abstract |
The invention relates to a microporous and mesoporous carbon xerogel and organic precursors thereof based on a phenol-formaldehyde xerogel. A characteristic parameter common to carbon xerogels is a peak in the mesopore size distribution determined by the BJH method (Barrett-Joyner-Halenda) from nitrogen absorption measurements at 77 K in the range from 3.5 nm to 4 nm. The production process is characterized firstly by the low starting material costs (use of phenol instead of resorcinol) and secondly by very simple and cost-effective processing; convective drying without solvent exchange instead of supercritical drying or freeze drying. The carbon xerogels and their organic phenol-formaldehyde xerogel precursors have densities of 0.20-1.20 g/cm3, corresponding to a porosity of up to 89%, and the xerogels can also have a relevant mesopore volume. The carbon xerogels obtained from the phenol-formaldehyde xerogels are also microporous. |
