NH3 is one of the most important chemicals in today's world, as it is used in the production of fertilizers to boost agricultural yields and sustain the ever-growing global population. For over 100 years, NH3 production has relied on the Haber–Bosch (HB) process, which combines nitrogen (N2) and hydrogen in the presence of a catalyst. Interestingly, an iron-based catalyst developed a century ago (called "Promoted-Fe") still remains at the forefront of mass NH3 production, despite countless efforts to find more energy-efficient alternatives. In the HB process, where NH3 is produced by a catalyst-filled reactor with a limited volume, the NH3 productivity in the reactor depends on the NH3 production rate, not per catalyst weight but per catalyst volume. While the former looks like the latter at a glance, these two are completely different.
