Abstract:Biochar is a product obtained from processing of waste biomass. The main application of biochar is in soil and environment remediation. Some new applications of this carbonaceous material take advantage of its adsorption capacity use it as a heterogeneous catalyst for energy storage and conversion etc. This contribution describes thermal stability of the original biochar. It discusses biochar modifi ed by chemical and physical methods including a new compound of biochar-graphene oxide. The purpose of the modifi cations is to increase its active surface to introduce active functional groups into the carbon structure of biochar in relation to fi re safety and toxicity of those products.
This contribution contains data on thermal stability of certain materials whose initial precursor is graphite. Graphite was oxidized separately and in a mixture with fullerene C 60. The prepared oxides were processed with vacuum filtration to produce foils and their morphology and thermal stability was described. The graphene oxides reacted with nano-cellulose and ß-glucan to produce composites. The prepared composites in the form of foils were tested for thermal stability and further analyzed e.g. by FT-IR, SEM, etc.
