Plasmon Power – Ambient Synthesis of Ammonia

The synthesis of ammonia by photoelectrochemical N2 reduction, unlike the century old high temperature high pressure Haber-Bosch ammonia process, is not very energy‐intensive and can operate at low or even ambient temperature and pressure. In a Chinese-Canadian collaboration, spearheaded Professor Jinlong Gong and Professor Geoffrey Ozin, the promotional role of surface O vacancies in outer layers of amorphous TiO2 thin films enable the adsorption and activation of N2 to facilitate N2 reduction to NH3 is described for the first time. The paper entitled “Promoted Fixation of Molecular Nitrogen with Surface Oxygen Vacancies on Plasmon‐Enhanced TiO2 Photoelectrodes”.
