The nitrogen (N 2 )‐to‐ammonia (NH 3 ) fixation driven by renewable energy has an attractive prospect to relieve the global warming and reduce the consumption of fossil fuels. Ideally, photocatalytic, electrochemical, and photoelectrochemical approaches are developed as the next‐generation NH 3 synthesis technologies to substitute the Haber–Bosch method. However, the NH 3 yield rate of nitrogen reduction reaction (NRR) by green approaches is extremely low, resulting in the current dilemma of NRR and contamination issues. Thus, in this mini review, the past advances on the sustainable NRR are briefly summarized in the three aspects as follows: the selectivity and adjustment of various catalysts, the type of electrolyte/solvent system, and the investigation of reaction conditions. Subsequently, the recent critical activities in the area of sustainable NH 3 synthesis are analyzed and discussed deeply, and a perspective for rational and healthy development of this area is provided positively.
