Photocatalytic Nitrogen Fixation Coupled with the Generation of Value-Added Chemicals from N and Cellulose over MoO Nanosheets.

Photocatalytic nitrogen fixation from N provides an alternative strategy for ammonia (NH) production, but it was limited by the consumption of a sacrificial electron donor for the currently reported half-reaction system. Here, we use naturally abundant and renewable cellulose as the sacrificial reagent for photocatalytic nitrogen fixation over oxygen-vacancy-modified MoO nanosheets as the photocatalyst. In this smartly designed photocatalytic system, the photooxidation of cellulose not only generates value-added chemicals but also provides electrons for the N reduction reaction and results in the production of NH with a maximum rate of 68 μmol·h·g.
