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.
