| Summary: | Abstract A simple two step synthetic method for di‐doped crystalline mesoporous tin dioxide powder containing antimony and fluoride at ambient pressure and temperature has been developed. This approach produced materials with high surface areas and improved electrical and optoelectrical conductance. The two dopant elements; antimony and fluoride were introduced to tin dioxide by two approaches. Both approaches produced mesoporous tin dioxide with antimony and fluoride that are integrated in the framework. The structures of these materials are analyzed by powder X‐ray diffraction, N2 sorption analysis, transmission electron microscopy, energy dispersive X‐ray spectroscopy and X‐ray photoelectron spectroscopy. The conductance of the materials improved by factor of 13–34 compared to undoped mesoporous tin dioxide. The effect of the di‐doped elements on structure, conductance and optoelectronic properties of these materials are discussed in this paper. |
