Co-synthesis of large-area graphene and syngas via CVD method from greenhouse gases

摘要

In this study, we report a novel and efficient way to produce large-area graphene and syngas simultaneously from CH_4 and CO_2 via CVD. The successful synthesis of syngas was confirmed by online gas chro-matography characterization whereas the graphene produced within the same process was verified using Raman spectroscopy, Raman mapping and HRTEM. This work helps to better understand graphene growth from CH_4 and CO_2 and improve the CVD method by providing a novel pathway for the synthesis of large-area graphene with a valued by-product. With our derived CVD approach, graphene was grown while producing syngas and consuming green-house gases which is of great importance in this current climate change phenomenon.
