AI Technical Summary

Technical Problem

The lack of standardized titanium dioxide materials in existing technologies makes it difficult to meet the needs of quality control, laboratory evaluation, and product calibration, especially in terms of particle size uniformity, band gap width, and sphericity.

Method used

Mesoporous spherical TiO2 with uniform particle size and high sphericity was prepared by using a mixed solution of ethanol, acetonitrile, ammonia and tetrabutyl titanate in a specific ratio, combined with calcination treatment, with the particle size controlled in the range of 100~600nm.

Benefits of technology

The particle size uniformity and sphericity of mesoporous spherical TiO2 meet the requirements of standard substances, exhibiting good stability and repeatability. It is suitable for instrument calibration and quality control, and meets the testing standards in the fields of optical performance calibration and food additives.
