Characterization of an AgCl/Al2O3 catalyst for lean NO conversion
文献情報
An AgCl/Al2O3 catalyst calcined at 873 K in air is highly active for the conversion of lean NO with ethanol even in the presence of SO2. The chemical and physical characteristics of the AgCl/Al2O3 catalyst were studied using X-ray diffraction, X-ray photoelectron spectroscopy and ultraviolet-visible (UV-VIS) spectroscopy. Crystallized AgCl particles were formed for the AgCl/Al2O3 catalyst calcined above 393 K in air. AgCl particles began to disperse on the Al2O3 surface upon calcination at 773 K. Dispersion of the AgCl particles progressed upon calcination at 873 K. UV–VIS spectra also showed an intense absorption band at ∽250 nm for the AgCl/Al2O3 catalyst calcined at 873 K which can be attributed to the AgCl on Al2O3. Surface silver content in the AgCl/Al2O3 catalyst calcined at 873 K is ∽4.2 times that of the AgCl/Al2O3 catalyst calcined at 773 K. These results suggest that effective NO conversion over the AgCl/Al2O3 catalyst calcined at 873 K in air is ascribed to the AgCl particles being well dispersed by interaction with Al2O3.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
