The aim of this thesis was the synthesis of carbon nanomaterials and their composites for environmental applications, application as an antibacterial agent, and crop protection. As the basic constituent of all prepared nanomaterials, graphene oxide (GO) prepared by the modified Hummers method was successfully used. In order to improve the desired properties, the prepared GO was further reduced and modified with magnetic nanoparticles (MPs) and nanoparticles (NPs) of metals or metalloids to form composites. In the prepared nanocomposites, the synergistic effect of graphene oxide and nanoparticles was utilized. In the case of nanocomposite formed from reduced graphene oxide (rGO) and MPs, this composite was used to bind Se (IV) as a heavy metal from an aqueous medium. In addition, the advantage of this material was its reusability after a recovery in ethanol. To protect agricultural crops against Xanthomonas euvesicatoria (X. euvesicatoria), which causes the bacterial spot disease of tomato and pepper and considerable economic casualties, nanocomposite containing GO and copper and silver NPs was used. This nanocomposite was selected for application to tomato and pepper plants after previous microbiological tests in vitro.
