Improving ammonia synthesis: New iron-based catalyst surpasses century-old benchmark

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.
