摘要
Ammonia is a key component in fertilizer and the carbon-free hydrogen carrier.Catalytic ammonia synthesis and utilization have played a central role in the development of chemical engineering.The industrial production of ammonia remains dependent on the energy-and carbon-intensive Haber-Bosch process.A major effort has been devoted to developing robust and efficient catalysts,as well as alternative benign processes.Herein,we detail our endeavors that develop the ammonia synthesis and decomposition catalysts,and utilize the ammonia energy.We firstly discuss the catalysts for ammonia synthesis via dissociative and associative process,and the regulation of catalysts'properties.Then,we review the burgeoning electrocata-lytic nitrogen reduction process,focusing on the enhanced catalytic performances by the regulation of the catalysts and the electrode.Additionally,we provide a novel high-value utilization of ammonia to achieve the"zero-carbon"circular economy.The promising catalysts,reactors,and ammonia energy systems have been discussed in detail.We end this Account that offers future research directions and prospects of ammonia.
