Because its tunable electrical, optical, mechanical and chemical properties, graphene oxide-based materials are currently of great interest in applications ranging electronics and communications, water treatment, medicine, energy storage and generation, mechanics and lubrication, between other. One advantage of these materials is the use of relatively abundant elements or the reduced use of scarce ones compared with bulk applications. The main disadvantage is the scale up of graphene oxide production. Our research group, Materials and Technologies for Energy, Health and Environment (GESMAT), designs and synthesizes graphene oxide-based materials in a lab-scale basis, using simple chemical, hydrothermal or electrochemical methods. Decorated materials have applications for electrocatalysis in microbial fuel cells, adsorption of dyes and heavy metals in water, possible agents in cancer detection and hyperthermia/drug delivery treatments, additives for increased lubrication and electrodes for solar cells. Graphene-based composites are intended for mechanical applications, air and water filters, CO2-reduction and H2-generation catalysts, solar fuel production and for supercapacitors. Coatings can be applied as barriers for corrosion protection or protective coatings for radiation impact. Our materials testing is regularly performed in national or university laboratories as part of MSc or PhD formation and scientific publications.
