description

The recent developments of the research in the field of dinitrogen reduction to ammonia at mild conditions of pressure and temperature are reported. After a brief historical recapitulation of the traditional thermal process, the new routes for NH3 synthesis (biological photosynthesis, direct electrochemical reduction, and photocatalytic reduction) are presented and critically discussed. A particular attention is devoted to heterogeneous photocatalytic reduction performed by irradiating pure, mixed, and doped semiconducting catalysts in gas-solid and liquid-solid systems. The fixation of dinitrogen in aqueous solutions containing complexes and photoactive particulate systems is also reported. Finally the studies related to the determination of the relation between the activity and the intrinsic properties of the photocatalysts are reviewed.
