Reducibility of Ni, Co, and Fe on γ-Al 2 O 3 governs both DRM activity and nanostructured carbon growth: Ni yields filamentous carbon via tip-growth, Co forms graphitic deposits via surface diffusion, and Fe remains catalytically inactive.

Abstract The paper shows the structural changes of copper and nickel catalysts in the presence of strong (O 2 ) and weak (H 2 O) oxidizing agents and their influence on the course of methane conversion. The changes in oxidation states of investigated catalysts were studied during partial oxidation and steam reforming of methane using an X‐ray reactor chamber (XRD) coupled with an online mass spectrometer. Also, the susceptibility of these catalysts to oxidation and reduction by individual reaction components was investigated using TPR, TPO, and in situ XPS techniques. The obtained results indicated the distinct catalytic behavior of copper and nickel catalysts depending on their oxidation state and the importance of coke formation in the activation of the partial oxidation process. The mechanism of re‐reduction of catalysts under reaction conditions and a method to increase the activity of nickel catalysts are proposed.

The investigation of the course of the Boudouard reaction and methane cracking was performed over nickel catalysts based on oxides of calcium, aluminum, and magnesium. The catalytic samples were synthesized by the impregnation method. The physicochemical characteristics of the catalysts were determined using atomic adsorption spectroscopy (AAS), Brunauer–Emmett–Teller method analysis (BET), temperature-programmed desorption of ammonia and carbon dioxide (NH3- and CO2-TPD), and temperature-programmed reduction (TPR). Qualitative and quantitative identification of formed carbon deposits after the processes were carried out using total organic carbon analysis (TOC), temperature-programmed oxidation (TPO), X-ray diffraction (XRD), and scanning electron microscopy (SEM). The selected temperatures for the Boudouard reaction and methane cracking (450 and 700 °C, respectively) were found to be optimal for the successful formation of graphite-like carbon species over these catalysts. It was revealed that the activity of catalytic systems during each reaction is directly related to the number of weakly interacted nickel particles with catalyst support. Results of the given research provide insight into the mechanism of carbon deposit formation and the role of the catalyst support in this process, as well as the mechanism of the Boudouard reaction.
