Abstract

An FeCrAl-fiber-structured NiO-MgO-Al₂O₃ nanocomposite catalyst engineered from nano- to macro-scale in one-step is developed via thermally decomposing NiMgAl layered double hydroxides (LDHs) that can be grown onto the FeCrAl-fiber only through a γ-Al₂O₃/water interface-assisted method. By taking advantages of homogeneous component-distribution in the LDHs-derived NiO-MgO-Al₂O₃ nanocomposites and enhanced heat transfer, this promising catalyst delivers satisfying performance with enhanced coking/sintering resistance in the title reaction. At 800 °C and a gas hourly space velocity of 5000 mL g^-1 h^-1, CH₄/CO₂ conversion maintains almost constant at 91%/89% within the initial 90 h and then slides in a smooth downturn (to 80/85%) within another 180 h of reaction.
