Abstract
We report the synthesis of crystallite mesoporous tin dioxide framework that contains nano gold clusters confirmed and analyzed by BET, XRD, HRTEM, XPS and UV-visible. The material has a surface area of 97 m2g-1, average pore sizes of 2.7 nm and pore volume of 0.08 cm3g-1. We believe that initially the nano gold clusters occupy the pores of the mesoporous tin dioxide, which restricted their further growth, then some of which diffused to the walls during the heat treatment. The average nano gold clusters are 1.2 nm. The material has a band gap of 2.9 eV that been determined using KubelKa- Munk function. This material would be used for gas sensing and/or optical catalysis.
