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: Pd-Au bimetallic catalysts often display enhanced catalytic activities and selectivities compared with Pd-alone catalysts, often caused by two alloy effects, i.e., ensemble and ligand effects.

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.

TL;DR: Detailed reaction kinetics are reported on low-temperature standard NH3-SCR, supplemented by DFT calculations, as strong evidence that the low-Temperature oxidation half-cycle occurs with the participation of two isolated CuI ions via formation of a transient [CuI(NH3)2]+-O2-[CuI (NH3]2]+ intermediate.

TL;DR: In this paper, the results of a variety of catalyst characterization and reaction kinetics measurements were presented, including surface area/pore volume measurements, temperature programmed reduction by H2 (H2-TPR), NH3 temperature programmed desorption (NH3-TPD), and DRIFTS and solid-state nuclear magnetic resonance (NMR) spectroscopies.
