摘      要：Ammonia (NH3) is not only an essential chemical feedstock for the manufacture of nitrogen-rich fertilizers but also a promising carbofree energy carrier for storing H2 due to its high content of hydrogen (17.6% by mass). At present, industrial NH3 is still dominantly produced by the traditional Haber-Bosch process, which reduces nitrogen (N2) to NH3 (N2+3H2←→2NH 3) at high temperatures (350-550 °C) and high pressures (150-350 atm)[1]. Such a process not only requires the raw materials of high-purity streams of nitrogen and hydrogen but also consumes tremendous energy;noting that the consumed hydrogen occupied approximately 50% of its global production that produced exclusively from transformations of fossil resources with the emission of greenhouse gas [1].
