Photochemical removal of NO2 in air at atmospheric pressure using side-on type 172-nm Xe2 excimer lamp

Catalyst-free photochemical CO2 hydrogenation to CO and CH4 conversion to C2H6

“…9,10 High-energy photons are known as the ideal initiators of chemical reactions and effective tools for analyzing the physical and chemical properties of small molecules. [11][12][13] In previous studies, the photolysis of CO 2 was conducted using a 146 nm Kr 2 excimer lamp as the light source, validating the availability of high-energy photons for CO 2 transformation; however, the product yield was low. 14 Nevertheless, the direct application of high-energy photons to drive CO 2 hydrogenation may further increase the yield but still remains relatively uncharted.…”
