In this study, we synthesized and scaled up Ru catalysts using high porosity MOF templates grown on graphitic carbon supports via solvothermal synthesis. Thermal treatment of the MOF resulted in well-dispersed Ru nanoparticles that were fully stabilized by in-situ graphitization of the surrounding carbon. The resulting catalyst showed significant improvement in activity for low-temperature NH3 synthesis, and the production of catalysts was scaled up from 1 g per batch to 200 g per batch.
We report the synthesis and scale-up of Ru catalysts that use high porosity MOF templates grown on graphitic carbon supports via solvothermal synthesis. Thermal treatment of the MOF resulted in well-dispersed Ru nanoparticles that are fully stabilized by in-situ graphitization of the surrounding carbon. The resulting catalyst has demonstrated significant improvement in activity for low-temperature NH3 synthesis, and catalyst production has been scaled up from 1 g per batch to 200 g per batch scales.
