Investigating the Ag–Support Interaction in Silver Catalysts for Soot Combustion: The Importance of Coordination of Al3+ Ions in the Support

Reactions, Journal Year: 2025, Volume and Issue: 6(2), P. 27 - 27

Published: April 18, 2025

This study shows how important the coordination of Al3+ ions in silver support is for overall activity soot combustion. Five catalysts with a content 14.7 wt.% were prepared using following supports: α-Al2O3, which has only octahedrally coordinated Al3+, θ-Al2O3, both and tetrahedrally zeolites, contain Al3+: 10X, 13X, 5A. The analysis diffraction patterns showed that on surface made first four supports was mainly metallic form, except Ag/5A there lack reflections from Ag0 XRD pattern. Nevertheless, difference catalyst as well EDX results indicate presence catalyst. SEM-EDX dispersion strongly depends even zeolites large particles have evenly distributed across surface. decreased series: Ag/Al 1200 > ≈ Ag/13X Ag/10X 550. Time-of-Flight Secondary Ion Mass Spectrometry used to delve into reason why low-surface area α-Al2O3 yielded better than obtained high-surface alumina different ratios secondary emitted two surfaces.

Toward synergetic reduction of pollutant and greenhouse gas emissions from vehicles: a catalysis perspective

Chemical Society Reviews, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 17, 2024

It is a great challenge for vehicles to satisfy the increasingly stringent emission regulations pollutants and greenhouse gases. Throughout history of development vehicle control technology, catalysts have always been in core position aftertreatment. Aiming address significant demand synergistic gases from vehicles, this review provides panoramic view technologies key aftertreatment using fossil fuels (gasoline, diesel, natural gas) carbon-neutral (hydrogen, ammonia, green alcohols). Special attention will be given research advancements catalysts, including three-way (TWCs), NO
