BIOLOGICAL PROCESS FOR THE OBTAINING OF REDUCED GRAFAN OXIDE, USING MICROORGANISMS
ES2695310
This invention proposes a method for the reduction of graphene oxide by the use of microorganisms comprising the following steps: reactivation and cultivation of the microbial biomass; preparation of a medium where the reduction process occurs, either on the solid graphene oxide or dispersed in an aqueous medium; and the contribution of a microbial element that produces the reduction of the oxide; where the aqueous medium occurs this reaction is tap water without any additional treatment, such as the additional contribution of nutrients or carbon sources, very common in other microbial cultures or a sheet of graphene oxide. Likewise, the temperature at which the reaction occurs is what could be considered "room temperature" and the process can be performed under aerobic conditions, but both characteristics must respect the limits and requirements of the microbial element to allow its growth. This process develops under simple conditions, because it is a passive microbial process that indirectly depends on the microbial metabolism.

En los últimos años, la síntesis del grafeno ha tenido un impacto notable por sus novedosas y amplias aplicaciones. Sin embargo, trabajos recientes muestran procesos de fabricación con métodos químicos, electroquímicos o térmicos optimizados y escalables pero altamente contaminantes. Siguiendo las directrices que marca el Pacto Europeo 2050, nuestro trabajo demuestra como el uso de microorganismos para la biosíntesis de grafeno es un proceso no solamente económico sino también sostenible a partir de principios básicos de la química y la biología.
