Single-Step Synthesis of a Highly Active Visible-Light Photocatalyst for Oxidation of a Common Indoor Air Pollutant: Acetaldehyde

A Ti‐Cr‐MCM‐48 photocatalyst prepared in a single step exhibits superior photocatalytic activity compared to TiO2‐Cr‐MCM‐48 prepared by a post‐impregnation method. The high activity of the photocatalyst is attributed to the synergistic interaction between the Cr ions dispersed in the silica framewor...

Summary:A Ti‐Cr‐MCM‐48 photocatalyst prepared in a single step exhibits superior photocatalytic activity compared to TiO2‐Cr‐MCM‐48 prepared by a post‐impregnation method. The high activity of the photocatalyst is attributed to the synergistic interaction between the Cr ions dispersed in the silica framework and the nanocrystalline nature of titania crystallites anchored onto the pore walls (see Figure).
