Novel direct synthesis of mesoporous tin dioxide network intact up to 500°C

This project is supported by PAAET project no. BE-­‐13-­‐08 in collaboration with Kuwait University and the University of York. The support of the research administration of Kuwait University to the XPS instrument (Project No. GS02/08) is acknowledged.We present a direct soft templating method to synthesise mesoporous tin dioxide network that maintains a porous structure after calcination at 400 °C and 500 °C and has a relatively high BET surface area of 220 and 100 m2 g-1, respectively. TEM, BET and XRD results confirm that both crystal and pore sizes increase as a result of increasing the temperatures during the calcination step. This method is highly reproducible.PostprintPeer reviewe
