Synthesis and Photocatalytic Activity of Submicron Strontium Titanate in Soluble Polymer System

Recently, micro-nano-strontium titanate photocatalytic materials have been one of the research hotspots because they can degrade organic pollutants. In the work, 200-400 nm strontium titanate powder was synthesized by soluble polymer (PEG) system and low-temperature direct precipitation method. Stud...

Description
Summary:Recently, micro-nano-strontium titanate photocatalytic materials have been one of the research hotspots because they can degrade organic pollutants. In the work, 200-400 nm strontium titanate powder was synthesized by soluble polymer (PEG) system and low-temperature direct precipitation method. Studies showed that the concentration of PEG and the degree of polymerization had a significant effect on the particle size of the powder. At the same time, the work studied the photocatalytic properties of the obtained strontium titanate powder, discussing the effect of particle size of strontium titanate on its photocatalytic activity.
