CTC presents innovative nanocomposites from graphene oxide at an international congress

The CTC Technology Centre has obtained a silica and graphene oxide material bearing very novel morphology and properties. The Centre’s researchers, who have developed this work in collaboration with the University of Cantabria, have managed to introduce graphene into mesoporous structures. They presented this truly innovative advance at the poster session of the 30th International Conference on Diamond and Carbon Materials, which is being held in Seville until the 12th of September. 

High-level international projects on a wide range of carbon-based materials are being presented at this event. Specifically, research by CTC and UC has resulted in nanocomposites of silica/graphene oxide and reduced silica/graphene oxide. Thanks to the intercalation of silica between the graphene oxide sheets, composite materials with a laminar structure and a specific surface area of 446 and 710 m2/g, respectively, have been achieved.

The generation of this type of ordered structures—in this case, laminar—with high specific surface implies the creation of ad hoc supports for different functions. CTC aims to obtain the appropriate support for its subsequent amino functionalisation and its use in the selective capture of CO2.

The  new nanostructures have been characterised through various scientific procedures such as X-ray diffraction, TEM, thermogravimetric analysis or differential scanning calorimetry (DSC) analysis, among others.

Elsevier, renowned worldwide for managing scientific information, is the organiser of this congress, which is one of the benchmark events in the area of carbon-based composite materials. Among the planned topics, there will be in-depth discussions on issues such as the deposition and doping of diamonds, the physical and chemical modification of carbon materials, Diamond devices for power electronics, optoelectronics and sensors, nanodots… In addition, two awards will be given during the congress: the DCM Young Scholar Award and the DCM Early Career Research Award; both stimulus to encourage the participation of the next generation of scientists and contribute towards creating a professional forum in which to exchange the latest results of cutting-edge research in diamonds and carbon materials.
