In this work, sulfur-doped mesoporous TiO2 films were formed by a chemical solution deposition technique to investigate their structure and electrical conductivity. Phase formation and crystallization of TiO2 was retarded and the optical band gap was reduced due to the presence of the sulfur dopants. As a result, enhancements in the microstructural stability and electrical conductivity of mesoporous TiO2 could be obtained by sulfur doping.
