| Abstract Scope |
We have developed a sustainable approach to produce bio-graphene. The presentation will cover the challenges facing graphitization of biomass polymers such as cellulose and lignin which are poorly graphitizable material, and how we have successfully obtained a graphite-like structure with multi-layers of graphene sheets using iron and calcium as non-toxic and abundant catalysts. The applications targeted for these sustainable and hierarchical carbon materials are energy storage, water sanitation and sustainable building materials. Experiment and simulation have been used to uncover atomic arrangements and the nanostructure of the carbon produced from the graphitization of cellulose at various temperatures and iron concentrations. We demonstrate that iron surfaces/sites likely act as ideal locations for nucleation and growth of graphene sheets and thus lower the activation energy for graphitization in traditionally non-graphitizable bioresources. We also evidenced the mechanism driving the graphitization of the biomass using calcium catalysts. |
