Abstract

The invention discloses a preparation method of a strontium titanate nano material with an adjustable morphology. The method comprises the following steps: uniformly mixing a strontium nitrate solution, a sodium hydroxide solution, a butyl alcohol solution of n-butyl titanate and a butyl alcohol solution of oleic acid, and carrying out a hydrothermal reaction at 100-200 DEG C for 6-24 hours to obtain the strontium titanate nano material. Through the influence of micelles formed by self-assembly of oleic acid molecules on the dynamic behavior of directional adsorption of SrTiO3 nano micro-crystals, the morphology is finally regulated and controlled, and the prepared SrTiO3 nano material is good in dispersity, high in photocatalytic efficiency and beneficial to later application of photocatalytic devices.

Description

technical field

[0001] The invention relates to a method for preparing a strontium titanate nanomaterial with adjustable morphology, belonging to the technical field of nanomaterial preparation Background technique

[0002] Strontium titanate (SrTiO 3 ), as a typical perovskite metal oxide, is a widely used electronic functional ceramic material, which has the characteristics of good thermal stability, low dielectric loss and high dielectric constant. played an important role in the application of materials. SrTiO 3 With good photocatalytic activity and suitable band gap (3.2-3.8eV), it has broad application prospects in the fields of photochemical cells, photocatalytic hydrolysis, and photocatalytic degradation of organic pollutants. SrTiO 3 The growth process and morphology control of crystals have an important impact on their physicochemical properties, since their structure dependence can be tuned by controlling the growth parameters and process.
