Article: Hierarchical structure nano-photocatalytic materials in interior decoration design Journal: International Journal of Materials and Product Technology (IJMPT) 2024 Vol.69 No.3/4 pp.179 - 198 Abstract: With the development of the social economy and the improvement of people's living standards, the demand for housing and accommodation conditions also increases. In the decoration design, but in the decoration process, the harmfulness of formaldehyde, paint, toxic gases, and other pollutants to the human body has to be prevented, and ensuring the safety of the living environment has become the focus of more and more people. In this paper, the titanium-containing multi-level nanomaterial TiO2 is applied to the decoration design, the photocatalytic properties of TiO2 are used to degrade indoor toxic substances, and the TiO2 photocatalytic materials are modified to improve the photocatalytic properties of TiO2. In the experiment, the performance of the multi-level structure nano-TiO2 to degrade formaldehyde was analysed. The formaldehyde concentration of the two filter samples was the same. After 20 hours, the needle-punched non-woven fabric was finished, the absorption liquid concentration decreased from 0.785 mg/L to 0.082 mg/L, and the formaldehyde purification rate reached 89.6%. Still, the activated carbon filter was absorbed, and the formaldehyde purification rate reached 94.4%, higher than 4.8% of needle-punched non-woven fabrics. Experiments have shown that nano-TiO2 has an obvious effect on purifying indoor formaldehyde. Inderscience Publishers - linking academia, business and industry through research

Abstract: With the development of the social economy and the improvement of people's living standards, the demand for housing and accommodation conditions also increases. In the decoration design, but in the decoration process, the harmfulness of formaldehyde, paint, toxic gases, and other pollutants to the human body has to be prevented, and ensuring the safety of the living environment has become the focus of more and more people. In this paper, the titanium-containing multi-level nanomaterial TiO₂ is applied to the decoration design, the photocatalytic properties of TiO₂ are used to degrade indoor toxic substances, and the TiO₂ photocatalytic materials are modified to improve the photocatalytic properties of TiO₂. In the experiment, the performance of the multi-level structure nano-TiO₂ to degrade formaldehyde was analysed. The formaldehyde concentration of the two filter samples was the same. After 20 hours, the needle-punched non-woven fabric was finished, the absorption liquid concentration decreased from 0.785 mg/L to 0.082 mg/L, and the formaldehyde purification rate reached 89.6%. Still, the activated carbon filter was absorbed, and the formaldehyde purification rate reached 94.4%, higher than 4.8% of needle-punched non-woven fabrics. Experiments have shown that nano-TiO₂ has an obvious effect on purifying indoor formaldehyde.
