TL;DR: A combination of ultrahigh magnetic field, solid-state magic-angle spinning nuclear magnetic resonance spectroscopy, and high-angle annular dark-field scanning transmission electron microscopy coupled with density functional theory calculations is used to reveal the nature of anchoring sites of a catalytically active phase of platinum on the surface of a γ-Al2O3 catalyst support material.

TL;DR: In this paper, the performance of a Cu ion-exchanged SSZ-13 zeolite in the selective catalytic reduction (SCR) of NO x with NH 3 was observed, in comparison with Cu-beta and ZSM-5 zeolites.

TL;DR: This review briefly discusses the structure and preparation of the CHA structure-based zeolite catalysts, and summarizes the key learnings of the rather extensive (but not complete) characterisation work, and provides some mechanistic details emerging from these investigations.

TL;DR: In this article, the effects of hydrothermal treatment on model Cu/zeolite catalysts were investigated to better understand the nature of Cu species for the selective catalytic reduction of NO{sub x} by NH{sub 3}.

TL;DR: In this article, the EPR and temperature-programmed reduction (TPR) results were used to identify the locations of the Cu2+ ion locations and the reaction kinetics of the NH3-SCR reaction.
