Aiming for high catalyst performance and enhanced coke resistance, different preparation techniques of La-promoted Ni/γ-Al<sub>2</sub>O<sub>3</sub> catalysts for DRM were compared facilitating structure-performance correlations. The studied synthesis techniques comprehend incipient wetness impregnation and co-precipitation as well as alternative techniques such as spray drying. All catalysts were fully characterized before and after reaction by N<sub>2</sub>-physisorption, XRD, H<sub>2</sub>-TPR and STEM-EDX elemental mapping. Additionally, a thorough investigation of carbon deposits has been carried out by TGA/DSC anRSC advances606-618https://www.ebi.ac.uk/biostudies/studies/S-EPMC9076903biostudies-literatureComparative study on La-promoted Ni/γ-Al<sub>2</sub>O<sub>3</sub> for methane dry reforming - spray drying for enhanced nickel dispersion and strong metal-support interactions.PMC9076903Prunte SPalkovits RSchneider JMBliznuk VPegios NSimeonov KfalseComparative study on La-promoted Ni/γ-Al<sub>2</sub>O<sub>3</sub> for methane dry reforming - spray drying for enhanced nickel dispersion and strong metal-support interactions.Dry reforming of methane (DRM) enables an efficient utilization of two abundant greenhouse gases by converting them into syngas, a versatile feedstock for chemical synthesis.
