Abstract Erionite (ERI) zeolite has recently attracted considerable attention for its application prospect in the selective catalytic reduction of NOx with NH3 (NH3‐SCR), provided that the high‐silica (Si/Al > 5.5) analog with improved hydrotherm

In this work, a series of ion exchanged Me-MFI zeolites (Me = Al, K, Ca, Mn, Fe, Co, Ni, Cu, Zn, Ga, Pd, Ag, In, Ir, Pt) was adopted as catalysts for the removal of NO and N2O by selective catalytic reduction (SCR) with NH3 and CH4. MFI zeolite struc

This paper introduces a joint industries–academia–academia research project started by researchers in several automobile companies and universities working on a single theme. Our first target was to find a zeolite for NH3-SCR, that is, zeolite mi

Bottom-up synthesis of titanosilicate nanoparticles was demonstrated with using a Ti-incorporated cubic silsesquioxane cage as a precursor. The catalytic tests suggest that well-dispersed and stabilized Ti species served as the active sites.

In situ/operando spectroscopic experiments and DFT calculations were combined to study the selective catalytic reduction of NO with NH3 (NH3-SCR) over Cu-AFX zeolites. Transient experiments (in situ/operando XANES, IR, and UV-vis) on the reduction ha

Dependence of NH3-SCR reaction rate on O2 partial pressure was investigated at 473 K over Cu ion-exchanged MOR, MFI, CHA and *BEA zeolites with varying “Cu density in micropores”. Among the zeolites, Cu–*BEA zeolite demonstrated promising poten

Direct conversion of methane into methanol at low temperature is a promising process for the efficient utilization of abundant methane as energy and chemical resources, and metal-loaded zeolites have been recently focused as a new candidate catalyst
