Abstract

concern because it is required for fertilizers, used in food production and many other applications. However, it relies on the Haber Bosch process, which requires a significant percent of the world energy and is responsible for an important amount of the CO2 world generation every year. This work tends to summarize the latest results and highest activity catalysts for the Nitrogen Reduction Reaction (NRR) at low temperature. The focus is set on electrochemical NRR, photocatalytic nitrogen fixation and photo electrocatalytic nitrogen reduction. Although an enormous effort was done by the scientific community, the performances of the catalysts are still several orders of magnitude lower from the industrial requirements. The different strategies and materials investigated are analyzed, and new trends and some ideas are proposed. This work tries to be a starting point for those who wish to start working on this fascinating topic of research. Keywords: Nitrogen fixation; Ammonia synthesis; Electrocatalytic;
