VISIBLE RAY-ACTIVE SPHERICAL CARBON-BASED POROUS MATERIAL, AND PREPARATION METHOD THEREOF

摘要

The present invention relates to a method for preparing a visible ray-active spherical carbon-based porous material, and more specifically, to a method for preparing a visible ray-active spherical carbon-based porous material (Ti-M-SCM) by supporting a titanium ion, which is a photoactive catalyst, to an ion exchange group of a strongly acidic cation exchange resin by an ion exchange method, additionally supporting transition metals to the ion exchange resin, and heat treating the same. The visible light-active spherical carbon-based porous material according to the present invention has photoactivity in the wavelength range extended to a visible light range and has the shape, size and strength appropriate for application to a commercial system, and thus can be used efficiently as a photocatalyst, an adsorbent and the like for removing an organic pollutant in the wide light wavelength range.
