Effective reduction of N2O emission via combined plasma catalysis

Catalysis Communications, 2023
N2O is a potent greenhouse gas that also causes devastating effects on the ozone layer. In this study, N2O decomposition is evaluated via thermal catalysis, plasma-alone and plasma catalysis, respectively. In thermal catalysis, N2O decomposition achieved

Dark catalysis [PDF]

Journal of Cosmology and Astroparticle Physics, 2017
Recently it was shown that dark matter with mass of order the weak scale can be charged under a new long-range force, decoupled from the Standard Model, with only weak constraints from early Universe cosmology. Here we consider the implications of an additional charged particle $C$ that is light enough to lead to significant dissipative dynamics on ...

Solar Energy Catalysis

Angewandte Chemie, 2022
When it comes to using solar energy to promote catalytic reactions, photocatalysis technology is the first choice. However, sunlight can not only be directly converted into chemical energy through a photocatalytic process, it can also be converted ...

Oxidation of propene from air by atmospheric plasma-catalytic hybrid system [PDF]

Journal of the Serbian Chemical Society, 2018
The pulsed dielectric barrier discharge (DBD) combined with the palladium supported on alumina beads, was investigated for propene (C3H6) removal from air. The effects of thermal-catalysis, plasma-catalysis (in-plasma catalysis and post-plasma catalysis),
