POROUS METAL CERAMIC MATERIALS AND METHODS FOR MAKING AND USING THE SAME

摘要

Aspects of the invention include porous ceramic materials and methods of preparing and using the same. The porous ceramic material may include a three-dimensional porous structure of fused clay ceramic and metal nanopatches. In some cases, the methods include providing a mixture including clay, a pore-forming agent, and a metal ion-containing component and heating the mixture under conditions sufficient to sinter the clay and the metal ion-containing component thereby forming a porous metal ceramic material. The pore-forming agent may be removed by combustion during heating. In some embodiments, the metal ion is silver, copper, or a mixture thereof. Also provided are methods of disinfecting a water source using the subject materials. Aspects of the invention further include compositions, e.g., materials, water treatment devices and kits, etc., that find use in methods of the invention.
