Abstract: A hollow mesoporous organic silica nano/microparticle having metal particles deposited thereon, and a method for preparing the same. The method may prepare a spherical nanoparticle by coating a porous organic silica layer on an inorganic silica particle having the metal particles deposited thereon and via selective etching of the layer. In addition, two or more types of metals pre-synthesized together with a magnetic particle, or different shapes of metals may be deposited on the nanoparticle at a target concentration. Thus, the nano/microparticle may be used for a drug delivery matrix, a catalyst, and a photothermal effect.

The method comprises providing a substrate (11) and depositing a first material (12) and particles (13) of a second material on the substrate, wherein the particles (13) of the second material have a higher melting point than the first material (12). Then, the substrate (11) with the first material (12) and said particles (13) is heated to a temperature where the first material (12) is melted and the particles (13) of the second material are not melted, wherein the first material (12) and the particles (13) are adhered to the substrate (11), wherein particles (13) are partly embedded in the first material (12) and form a rough surface. A ceramic material is deposited on the rough surface formed by the particles (13) to form a ceramic layer (14) thereon, wherein a catalytically active material (16) id added to the ceramic layer (14). Disclosed is also a catalytically active product.
