I am currently studying in the Surface Science Group in the Chemistry Department. The focus of my study is to investigate the ammonia synthesis catalyzed by the compound of FeSx which can be either in the form of nanoparticles or a bulk single crystal (i.e. pyrite single crystal). The aim is to understand why FeSx is able to catalytically reduce nitrogen to ammonia under benign conditions as occurs in extant biology (i.e. nitrogenase) from perspectives of the electronic structure and geometric size and shape. With this effort, it is hoped that a more energetically efficient process for ammonia synthesis can be developed with an aid of optimized biomimetic catalyst.
