The sol-gel method was used to synthesize sulfur-doped TiO2 powder using potassium persulfate as the sulfur source. Mesoporous nanocrystal aggregates were successfully created. The aggregates were 100nm wide and were composed of smaller 10nm TiO2 nanocrystals. The synthesis parameters, namely calcin...
