FT-IR spectroscopy with photoacoustic detector has been applied to investigate organic template transformations during thermal treatment of silica and silica-alumina MCM-41 molecular sieve. The role of surfactant degradation and type of organic deposits on silica surface remaining after surfactant elimination depends on the presence of alumina in MCM-41 pore network.
