Cover Feature: Silica‐based Materials for Mercury Detection and Removal: A Chelation‐Free Solution (Chem. Asian J. 8/2025)

A novel pyrene-functionalized silica material (PySiO₂) offers a highly effective solution for detecting and removing mercury ions (Hg2+) from water. This material exhibits excellent selectivity and sensitivity, achieving a remarkable 83% removal efficiency. The underlying mechanism involves a combination of charge-dipole and π-electron interactions, which facilitate the capture of Hg2+. Importantly, PySiO₂ can be reused, making it a promising and sustainable solution for water purification. More details can be found in article number e202401591 by Supavadee Kiatisevi and co-workers.
