A material floating on water and comprising a cork core coated with a layer of activated carbon and a layer of titanium dioxide, preparation process and use

摘要

A material floating on water and comprising a cork core surface coated with a layer of activated carbon of amorphous structure and a discontinuous layer of titanium dioxide on said activated carbon layer. The invention also describes the process for obtaining said material, which comprises conducting a physical or chemical activation cork calcining the material at a temperature between 500 and 850 ° C in inert atmosphere, impregnating the material from the previous step with water resulting pulverized and then with a titanium compound and drying the material resulting from the previous step. The invention also describes the use of such material as adsorbent and Photocatalytic decontaminant in the treatment of gaseous and liquid streams comprising organic contaminant compounds.
