METHOD FOR REDUCING ODOR USING METAL-MODIFIED SILICA PARTICLES

摘要

A method for reducing odor is provided. In one embodiment, the method comprises modifying the surface of silica particles with a transition metal so that the silica particles are bonded to the transition metal through a covalent or coordinate bond. The method further comprises contacting the modified silica particles with an odorous compound, the transition metal facilitating the capture of the odorous compound.
