Visible and NIR Light Assistance of the N(2) Reduction to NH(3) Catalyzed by Cs-promoted Ru Nanoparticles Supported on Strontium Titanate

[Image: see text] NH(3) production accounts for more than 1% of the total CO(2) emissions and is considered one of the most energy-intensive industrial processes currently (T > 400 °C and P > 80 bars). The development of atmospheric-pressure N(2) fixation to NH(3) under mild conditions is attr...

description [Image: see text] NH(3) production accounts for more than 1% of the total CO(2) emissions and is considered one of the most energy-intensive industrial processes currently (T > 400 °C and P > 80 bars). The development of atmospheric-pressure N(2) fixation to NH(3) under mild conditions is attracting much attention, especially using additional renewable energy sources. Herein, efficient photothermal NH(3) evolution in continuous flow upon visible and NIR light irradiation at near 1 Sun power using Cs-decorated strontium titanate-supported Ru nanoparticles is reported. Notably, for the optimal photocatalytic composition, a constant NH(3) rate near 3500 μmol(NH(3)) g(catalyst)(–1) h(–1) was achieved for 120 h reactions, being among the highest values reported at atmospheric pressure under 1 Sun irradiation.
