Abstract
A one‐pot synthesis of aluminium‐containing mesoporous silica particles (Al‐MSPs) utilizing polyvinyl alcohol (PVA) as steric stabilization agent is reported. PVA prevents particle agglomeration even when the ionic aluminium source is present in the synthesis mixture. Silicon and aluminium sources were utilised completely, resulting in high yield and easy adjustment of the Si/Al ratio. The Al‐MSPs showed a spherical morphology, high surface area and were active for the liquid‐phase Beckmann rearrangement of cyclohexanone to caprolactam.
Polyvinyl alcohol was successfully utilized as steric stabilisation agent for the synthesis of aluminium‐containing mesoporous silica particles (Al‐MSPs). The synthesized Al‐MSPs were characterized and tested as catalysts for the liquid‐phase Beckmann rearrangement of cyclohexanone to caprolactam.
