DARE2X - WP2 Synthesises - Supporting document to deliverable 2.2

Synthesis recipies and data for catalyst development in DARE2X project. The results are described in deliverable 2.2 from the project. Catalyst for plasma-catalytic synthesis of ammonia. Technical challenges prevent the realization of decentralized green NH3 production. The DARE2X project aims to overcome these challenges by utilizing non-thermal plasma to drive the reaction with novel catalysts and sorption materials. The objectives of Work Package 2 are to optimize plasma catalysts using less critical raw materials, to further improve catalyst activity with the addition of promoters, to increase NH3 yields by incorporating catalysts into sorption materials, and to upscale catalyst production. Catalyst materials were synthesized with a supercritical flow reactor and upscaled via wetness impregnation. Catalyst materials were benchmarked (Co, Ni, Cu, Ru, Pt, Fe, NiFe, NiCo, CoFe). The addition of promoters (Ca, Ba, La) and the incorporation of zeolite sorption materials were investigated.
