The photocatalytic activity of V-Leaf® under UV and normal light was tested by independent experts in photocatalysis at Manchester Metropolitan University. The approved method measuring photocatalysis was by monitoring the CO2 in a specific reaction and results are shown below. The material was 10 times more effective in photocatalysis, both under UV light and normal light compared to the unprocessed material.

Data generated confirmed the conversion of N2O, NO and NO2 to nitrate for plant use. The amount of nitrate produced is directly related to the ppm NOx concentration.
