TEM images of carbon/silica composites of different morphology
A variety of carbon-mineral composites (CMC), especially carbon-nanosilica and carbon nanoparticles bound to various solid matrices was prepared using different methods. There are CMC with nonporous and strongly porous carbons with the specific surface area of 50-1500 m2/g. The CMC characteristics are controlled by choice of precursors, reaction and treatment conditions.
There are several types of composites:
- mechanical mixtures differently treated;
- carbonized organics at a solid surface;
