SrTiO3 is an excellent photocatalyst due to its high photocorrosion resistance and thermal stability. In this study, we synthesized SrTiO3 nanoparticles with high specific surface areas by the hydrothermal method at reduced temperature. Titanium(IV) bis(ammonium lactato)dihydroxide (TALH) solution and strontium hydroxide octahydrate [Sr(OH)2·8H2O] were used as starting materials. SrTiO3 nanoparticles were directly synthesized by hydrothermal heating at 150°C for 72120 h. The synthesized nanoparticles had diameters of 2040 nm, and the SrTiO3 powder heated for 72 h exhibited the highest specific surface area of 33.1 m2/g. This sample also showed the highest degradation rate for NO gas.
