TiO2-SiO2 Nanoparticles with UV-shielding Effect and Reduced Photocatalytic Activity

Abstract

Here, we present the synthesis of multifunctional nanoparticles with suppressed photocatalytic activity, tremendous photoluminescence, great optical transparency and outstanding UV absorbance. The nanoparticles’ shape is shown by FESEM tests as fibrous linkages that resemble rods and have pores in between. According to the BJH analysis, the measured pore size was 20 nm. Ultraviolet light irradiation tests confirm the highly effective UV screening performance; nevertheless, the nanoparticles’ photocatalytic property was removed. In the whole 200 to 400 nm range, the UV transmittance is comparatively low, demonstrating the sample’s improved UV protection capability. The nanoparticles’ ultralow dimension, 2.49 m2 g-1 was discovered during a nitrogen adsorption/desorption test, which is in line with their phenomenally low photocatalytic capacity.
