  • MAGNETIC DYE-ADSORBENT CATALYST
    Publication number: 20130105397
    Abstract: New magnetic dye-adsorbent catalyst has been described in this invention, which is the modification of conventional magnetic photocatalyst. The catalyst consists of a composite particle having a core-shell structure, with a magnetic particle as a core and a dye-adsorbent (which may also exhibit photocatalytic activity) as a shell. The shell is made up of 1-dimensional (1-D) nanostructure, which enhances the specific surface-area of the conventional magnetic photocatalyst. The new magnetic dye-adsorbent catalyst removes an organic dye from an aqueous solution via surface-adsorption mechanism; while, the conventional magnetic photocatalyst uses the photocatalytic degradation mechanism.
