Catalytic decomposition of NO2 over a copper-decorated metal-organic framework by non-thermal plasma
Nitrogen oxide (NOx) causes significant impacts on the environment and human health, and nitrogen dioxide (NO2) is the most toxic and prevalent form of NOx in the atmosphere. Its removal and catalytic degradation into non-harmful species (i.e., N2) are thus important challenges. A great deal of effort has been devoted to developing catalysts for deNOx processes with a focus on NO reduction from ...

Element- and charge-state-resolved ion energies in the cathodic arc plasma from composite AlCr cathodes in argon, nitrogen and oxygen atmospheres
Cathodic arc plasmas are frequently applied to deposit wear-resistant coatings like Al-Cr-N and Al-Cr-O. The metals are introduced as cathodes which are eroded due to the interaction with the plasma. Placing substrates in the plasma stream, metal ions and atoms can condensate on the substrates and a film or coating can grow. Reactive gases like N2 or O2 are added in order to enable the synthesis ...
