Properties of Fine dust Adsorption Matrix using Rutile Type of TiO2

Abstract

Background/Objectives: Air pollution by fine dust is getting worse. As the occurrence of fine dust increases, it is affecting environmental pollution and the human body.

Methods/Statistical analysis: In this study, photocatalyst was used for fine dust adsorption. TiO₂ was used as a photocatalyst and the mechanism of TiO₂ was analyzed. Using the rutile type of TiO₂ was carried out for the comparison with the anatase used in the past. The test items were strength, density, water absorption, thermal conductivity, and adsorption experiment.

Findings: In this study, photocatalyst TiO₂ was used for fine dust adsorption. The hardened body was manufactured using the rutile type of TiO₂, The results are as follows. As the rutile increases, the density and the absorption rate decrease and the absorption rate increases. The fluidity decreases as the rutile absorbs the compounding water. As the substitution ratio of rutile increases, the strength tends to decrease. The thermal conductivity decreases as the replacement rate increases due to the occurrence of pores as the hardening progresses. As the curing progresses, the thermal conductivity decreases. When rutile was used, the catalytic action occurred while decreasing the fine dust concentration.

Improvements/Applications: As a result of using TiO₂ rutile, it was confirmed that the performance is lower than that of anatase. You'll have to come up with a way to outperform anatase.
