Special Issue Information

Dear Colleagues,

In 2021, the total global production of ammonia (NH3) was 150 million metric tons, reaching the highest level in nearly a decade. More than 80% of synthesized NH3 is currently consumed in the manufacturing of fertilizer to satisfy the demands of the increasing global population. In addition, NH3 is expected to be used as a carbon-free energy carrier because it can easily be stored and transported. Although some research has focused on nitrate (NO3-) hydrogenation to NH3, nitrogen (N2)-to-NH3 fixation still attracts considerable attention because its required components are green and plentiful. The main challenges for N2-to-NH3 fixation are the activation of N2 and sluggish reaction kinetics, corresponding to the strong bond energy of N≡N (940.95 kJ·mol-1) and the complex multi-step six-electron process, respectively.

Since the discovery of the Haber–Bosch (HB) process in 1909, it has been used to produce a large proportion of the global NH3 over the last 100 years. Practical NH3 production via the HB process has enabled the global population to nearly quadruple since the rapid implementation of the process in the early 20th century. However, to promote the rupture of N≡N and the hydrogenation reaction, the HB process requires high-temperature (400-500 °C) and pressure (10-20 MPa) reaction conditions, which accounts for around 1.5% of the total global carbon dioxide (CO2) emissions and consumes about 2% of the world’s annual energy supply. An alternative, green and environmentally efficient process for nitrogen (N2)-to-NH3 fixation with renewable energy needs to be pursued for sustainable NH3 production.

Submissions to this Special Issue, entitled “Advances in Catalysis in Nitrogen-to-Ammonia Fixation”, may take the form of original research articles and short reviews which reflect state-of-the-art work on N2-to-NH3 fixation through photocatalytic, electrochemical, photoelectrochemical and enzymatic routes on the following topics: the efficient catalytic conversion of N2 to NH3, catalyst research and development for the N2 reduction reaction (NRR), catalyst stability and deactivation, the catalytic mechanism, the kinetics and modeling of NRR, novel catalytic routes for NRR, and structure–functional relationships of catalysts.
