| Abstract | TiO2 and ZrO2 are known as superior inorganic materials in terms of chemical and physical stability. Therefore, these types of membranes are more suitable and preferable for filtration applications under harsh environments. However, it is difficult to control and achieve pure TiO2 and ZrO2 membranes with small pore size in the nanofiltration (NF) range (0.5-2 nm) due to their low phase-transformation temperature. To overcome this problems, composite mixed oxide membranes have been investigated. A limited number of studies have reported the development of TiO2-ZrO2 membranes for NF applications. However, as far as could be ascertained, no paper has ever reported in detail regarding the effect of the type of sols, firing temperature, and Ti/Zr ratio on the structure and performance of the membranes. In addition, no paper has ever reported hydrothermal stability and NF performance at high temperature of TiO2-ZrO2 membranes. Therefore, in order to optimize the membrane performance, TiO2-ZrO2 membranes with different type of sols, firing temperatures, and Ti/Zr ratios were prepared. Moreover, hydrothermal stability and NF performance at high temperature were evaluated. The main contributions of this research can be withdrawn from the following: |
