Using photocatalysis for sustainable agriculture: R-leaf's potential in large-scale N2O mitigation

Popis výsledku v původním jazyce

Addressing climate change through the removal of greenhouse gases (GHGs) is crucial for achieving global environmental goals. Nitrous oxide (N2O) has gained increasing attention due to its significant global warming potential—approximately 300 times that of CO2—and its rising atmospheric levels, largely driven by intensive agriculture. Among the various methods proposed for air pollutant removal, photocatalysis presents a promising and sustainable approach, especially if utilising solar light as an excitation source. This work investigates the photocatalytic removal of N₂O using R-Leaf, a TiO₂-based photocatalyst, under both controlled laboratory conditions and real-world field applications. In laboratory experiments conducted in a batch photoreactor R-Leaf achieved N₂O conversion rates between 6 % and 12 %, depending on initial concentrations and atmospheric conditions. Notably, in air, conversion efficiency increased, indicating a promising role for oxygen in enhancing photocatalytic activity. Finally, to demonstrate the potential of R-Leaf for applications in large agricultural areas, a small-scale field trial was performed. After application of the photocatalyst, approximately 1 ppbv of N2O was removed when compared with a nearby control field without the R-Leaf. While the observed change in N₂O concentration was relatively small, its impact is magnified by the vast scale of global agricultural land. These findings highlight R-Leaf&apos;s potential as a sustainable solution for decarbonizing agriculture, paving the way for large-scale photocatalytic air purification. © 2025
