The different synthesis conditions at smaller scale also require a rethinking of the existing HB iron catalysts, which have been optimized for large, low space velocity reactors. New, advanced heterogeneous catalysts, capable of 5X faster nitrogen fixation, will be discussed. This talk will detail the development of the catalyst, including the ternary oxide support and metal nanoclusters, both of which play a key role in the catalyst performance. Many phases of the ternary system were synthesized, characterized for surface area and metal dispersion, and tested in a differential reactor to map catalytic performance to support composition and structure. Additionally, different active metals were attached to the best performing oxide support, to study the activity dependence on metal species.
