Synthesis And Environmental Application of Nano Strontium Titanate

In recent years, perovskite compounds have become a hot spot in the field of photocatalysis due to their unique structures. Strontium titanate (SrTiO3) is a typical perovskite composite oxide, which has excellent properties such as high dielectric constant, low loss and good thermal stability, and its applicability in many fields is significantly better than that of traditional materials, and its application prospects are very broad. In this paper, the research progress of the synthesis of SrTiO3 nanoparticles at home and abroad is reviewed. The main methods include hydrothermal method, solid phase method, sol-gel method, chemical co-precipitation method, etc. Among them, the hydrothermal method and the solid-phase method have good industrial application prospect, and the synthesized products are of high quality, low cost, and easy to control the process. Moreover, SrTiO3 has a good application prospect in environmental protection, especially in wastewater treatment.
