Scientists from the University of Science and Technology of China in Heifei developed a simple and quick method of preparing "3D Graphene" in water - which they say can enhance Graphene so it is better suited to store hydrogen and act as a catalyst support in supercapacitors.
The scientists prepared the 3D graphene structures by self-assembly from graphene oxide using mild chemical reduction in water at 95 degrees Celsius (at atmospheric pressure) without stirring. The graphene shapes were controlled by using reactor vessels of differing shapes. The team were able to produce cylinder-, pear- and sphere-like shapes. The new materials features high electrical conductivity and high mechanical and thermal stability.
