Synthesis of Macro‐Mesoporous MCM‐41 and Its Use in Methylene Blue Adsorption

Thome, Andreas Georg / Harms, Corinna / Roessner, Frank

MCM‐41 was synthesized in the presence of yeast cells (Saccharomyces cerevisiae). The corresponding calcined material was characterized by scanning electron microscopy, X‐ray diffraction, nitrogen sorption, and mercury porosimetry and compared to MCM‐41 silica synthesized in the absence of yeast. The material synthesized with yeast cells showed equally sized ordered mesoporous silica particles arranged around macropores. These macropores are negative replica of the yeast cells. This material has superior methylene blue adsorption properties from aqueous solution in comparison to ordinary MCM‐41.
