Spatial Evolution of Coke in ZSM‐5 Catalysts During Methanol‐to‐Hydrocarbons Conversion Revealed by In Situ X‐Ray Photoelectron Spectroscopy

open access: yesAngewandte Chemie International Edition, EarlyView.
Coking is the central source of deactivation of zeolite catalysts. Using in situ XPS along with complementary methods, we identify differences in the formation kinetics and composition of surface coke on industrially relevant ZSM‐5 catalysts during MTH conversion, demonstrating the strong potential of this technique for studying catalyst deactivation ...

Evaluation of Methods for Formaldehyde Measurement in Industrial Emissions

open access: yes
Formaldehyde is a widely present pollutant in both indoor and outdoor air. Due to its high reactivity and carcinogenic nature, it poses serious health risks and measurement challenges. In fact, the International Agency for Research on Cancer (IARC) has classified formaldehyde as a Group 1 human carcinogen. As a result, countries like Italy have lowered
