Researchers from Australia’s James Cook University and Flinders University recently announced they successfully used cheap agricultural byproduct, nanocellulose, to make graphene – using only water, rather than harsh chemicals.
The team took cellulose derived from woody biomass, converted it to biochar, then used a newly patented vortex fluidic device (VFD) to produce high quality graphene, explained the paper’s first author and JCU PhD candidate Yu Matsueda. “The VFD rotates at very high speed, allowing us to really control the way fluids move inside the device … thus we can control the layers of graphene formed from the initial biochar,” he said “In our research we used water as a solvent, which is more sustainable than current methods.”
