This thesis focuses on the development of Ni-based catalysts for ethanol dry reforming, a route for the simultaneous valorization of renewable ethanol and CO2 into synthesis gas. Different synthesis strategies based on the epoxide-driven sol–gel approach and spray drying were investigated to establish relationships between catalyst structure, Ni accessibility, redox properties and catalytic performance. Particular attention was given to the influence of support morphology, catalyst composition and metal–support interactions on reaction stability and product distribution. The formation, structure and reactivity of carbon deposits were also examined, together with CO2-assisted carbon removal and surface reaction pathways. Combined catalytic testing, physicochemical characterization, kinetic analysis and in situ spectroscopy were used to clarify the factors governing catalyst stability during EDR.
