Reduced cobalt phases of ZrO2 and Ru/ZrO2 promoted cobalt catalysts and product distributions from Fischer–Tropsch synthesis

Promoting jet fuel production by utilizing a Ru-doped Co-based catalyst of Ru-Co@C(Z-d)@Void@CeO2 in Fischer Tropsch synthesis

“…Although the RNC catalyst exhibits higher X CO and Y C 5+ than the NC catalyst, it intensifies the selectivity towards methane up to 7.1% which is in accordance with the other reports. 9,49 MD simulation illustrated the same trend toward methane selectivity for the Ru-doped catalyst.…”

Oxidative Thermal Conversion of Hydrothermal Derived Precursors toward the Mixed-Metal Cobaltite Spinel Oxides (ZnCo2O4 and NiCo2O4): In-Situ Investigation by Synchrotron-Radiation XRD and XAS Techniques

“…Therefore, this work focuses on investigating the detailed phase transformation during the thermal treatment of two crystalline mixed-metal hydrothermal-derived precursors, for the synthesis of ZnCo 2 O 4 and NiCo 2 O 4 spinel materials. To understand the phase transformation mechanism in the subsequent thermal-oxidative step, in-situ X-ray diffraction (XRD) and time-resolved X-ray absorption (TRXAS) techniques were employed [42,43]. These two techniques allow a direct assessment and visualization in both the alteration of long-range and short-range ordering regarding the gradual vanishing of the precursor phase and the emerging formation of a desired crystalline mixed-metal spinel phase [44].…”
