Opis:: TiO2-ZSM-5/ceramic fiber composite was successfully prepared for the first time by impregnation and applied to remove toluene in the atmosphere and RhB in wastewater. Optional values for TiO2loading and calcination temperature were discussed. The composites were characterized by XRD, SEM, TEM, UV-vis and N2 adsorption-desorption. The results showed that TiO2loading amount affects the crystal formation, distribution, pore size and adsorption capacity for pollutants, which in turn determines the adsorption performance and photocatalytic activity of the composite. Composites calcined at 550 ℃ with 12.7 wt. % TiO2loading can degrade toluene and RhB most effectively, with the maximum degradation rates of 39.99% and 92.70%, respectively. In addition, materials have been proven to have high degradation stability being recycled 4 times. The TiO2-ZSM-5/ceramic fiber prepared in this study can degrade atmospheric and industrial wastewater pollutants. Therefore, TiO2-ZSM-5/ceramic fiber has high comprehensive practical value in the field of environmental pollutant removal.

Opis:: This paper describes preparation methodology and research results of newly developed materials from post-production fibrous waste that are resistant to high temperatures. Widely available raw materials were used for this purpose. Such approach has significant impact on the technological feasibility and preparation costs. Obtained materials were verified via applying of various tests including characterization of shrinkage, porosity, density and water absorption as well as X-ray analysis (XRD), followed by mechanical bending and compressive strength determination. Based on the research results, the possible applications of materials as thermal insulators were indicated.
