Abstract

SrTiO<sub>3</sub> is an excellent photocatalyst due to its high photocorrosion resistance and thermal stability. In this study, we synthesized SrTiO<sub>3</sub> 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)<sub>2</sub>·8H<sub>2</sub>O] were used as starting materials. SrTiO<sub>3</sub> nanoparticles were directly synthesized by hydrothermal heating at 150°C for 72–120 h. The synthesized nanoparticles had diameters of 20–40 nm, and the SrTiO<sub>3</sub> powder heated for 72 h exhibited the highest specific surface area of 33.1 m<sup>2</sup>/g. This sample also showed the highest degradation rate for NO gas.
