Macroestruturas tridimensionais de grafeno decoradas com nanopartículas de ferro para degradação de cafeína

Abstract

Contaminants from the scientific community have attracted attention from the scientific community, due to the harmful effects they can cause to human health and these to general health. These substances used for supply, in wastewater (in the range of µg/L or ng/L), reaching ecosystems used for public supply, in wastewater, with or without. The treatment carried out in the water stations is normally the conventional one that is not designed in the preparation of these contaminants. Caffeine is an emerging contaminant, whose substance is beverages and drugs, and it has been studied as a potential record of food activity found in tropical foods, as it is only used by humans in found foods. In this sense, it is necessary to develop treatments or materials that are still capable of removing environment-environment contaminants. In view of this, the objective of the present work is to develop graphene macrostructures decorated with iron nanoparticles for removal and alteration and can also serve other analogous substances. macrometrics as reducers of the presence of different three-dimensional metal trioxide precursors as reducers of ferrochemistry of the precursor of metal trioxide and with size reduction of surfactants agents in the presence of metal precursors and semi-lame reduction mechanisms of surfactants in the presence of metals trioxide iron precursors and three-dimensional and with reduction of sizes of surfactants agents in the presence of precursors. The materials were characterized by scanning electron microscopy (SEM), infrared spectroscopy (FTIR) and spectroscopy. From this, different iron results, from an environmentally friendly and one-step synthesis. Devastating tests were possible, positive results for all materials build degradation charts for each material, as there are analytical parameters interfering with the caffeine control solution. Finally, it is concluded that there is no different work to successfully obtain the threedimensional structures of graphene, and as successful techniques to characterize the best structures of each material and test the presence of iron nanoparts. Regarding the degradation tests performed, the materials used can be used in catalysis.
