Current ammonia synthesis, via the Haber Bosch process, produces >1% of global CO2 emissions, due to its reliance on methane derived H2. There is a burgeoning interest in electrochemical N2 reduction to NH3 at room temperature and under ambient pressures. Should it be powered by renewable energy, it would enable sustainable NH3 production, revolutionising the fertiliser industry. Should the process be efficient enough, it would even provide a means of producing a CO2-free energy-dense sustainable fuel. The aim of this project is to elucidate the role of the catalyst material (i.e. the electrocatalyst) and electrolyte and develop new systems that enable efficient nitrogen reduction. It will involve (a) catalyst synthesis and characterisation (b) testing H2 evolution and N2 reduction (c) measuring the products using a novel on-chip electrochemical mass spectrometry method.

当前的氨合成通过HABER BOSCH工艺，由于其依赖于甲烷衍生的H2而产生了> 1％的全球CO2排放量。在室温下和环境压力下，电化学N2降低到NH3的电化学N2迅速兴起。如果它由可再生能源提供动力，它将促进可持续的NH3生产，从而彻底改变肥料行业。如果该过程足够高效，它甚至将提供一种生产无CO2能量浓密可持续燃料的方法。该项目的目的是阐明催化剂材料（即电催化剂）和电解质的作用，并开发可有效氮的新系统。它将涉及（a）催化剂合成和表征（b）测试H2进化和N2还原（C）使用新型芯片电化学质谱法测量产物的N2。
