Making Haber-Bosch sustainable
Academic project
PhD
Open
Research question
The research will be directed towards addressing the following three questions: (i) What is missing in the current picture of the reaction mechanism, and how do off-equilibrium conditions affect intermediate distributions? (ii) How do promoter substances on the catalyst break universal scaling relations and how do they enable improved reaction conditions? (iii) What is the influence of different catalytic materials on electrochemical ammonia production and the concurrent processes?
Sustainability aspects
Ammonia has a higher energy density than hydrogen and can be more easily stored and transported for use in fuel cells, combustion engines or as the classical chemical feedstock for example in fertilizer production. Its production with the Haber-Bosch process though consumes lots of energy, requires an abundant source of natural gas and emits large amounts of CO2. Optimizing the production reaction parameters with a rationally designed catalyst will follow from a fundamental understanding of the reaction mechanism and how it can be influenced.
