Data confidence 85 high
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Cupric oxide (CuO)/iridium (Ir) (1/5 wt%) catalysts deposited on carbon nanotubes (CNTs) are considered to be adequate active catalysts for ammonium dinitramide (ADN) decomposition. In this study, the decomposition of ADN ionic liquid was performed over CuO crystallites deposited on Ir CNTs, which were highly distributed due to their high surface area. The catalyst activity was evaluated by calculating the turnover frequency (TOF) of CuO crystallites with different content amounts into the catalyst surface. The highest activity for ADN decomposition was demonstrated over CuO at 1 wt% due to its highest calculated TOF. The TOF was influenced by the presence of ammonium nitrate as an impurity in the ADN solution.
