“…The reduced state precursors will directly react with the carbon source. , It has been widely acknowledged that the Fe-based catalysts are usually coated with an amorphous carbon layer during FTS, which facilely induces the carbide transformation. , Recently, Li’s group have reported that the confinement of graphene layers favor the formation of ε-Fe 2 C from α-Fe . It has been reported that the pretreatment atmosphere and the intrinsic nature of the precursors would both affect the carbide formation. , According to the above discussions, it is considered that the glucose-induced carbon-rich atmosphere will benefit the reduction and carburization behaviors of iron oxide/graphene oxide catalysts. Various characterizations including transmission electron microscopy (TEM), X-ray diffraction (XRD), N 2 physisorption, X-ray photoelectron spectroscopy (XPS), temperature-programmed reduction (TPR), thermogravimetric analysis (TGA), and Mössbauer spectroscopy were applied to investigate the effect of glucose content on the structure and property of catalysts.…”
