An effective method for incorporating cadmium ions into mesoporous silica SBA‐15 is demonstrated. One of the novel features is the assembly of CdS nanoparticles inside the mesopores by selectively functionalizing the external surface of SBA‐15 in order to avoid the possible adsorption of the cadmium ions onto this surface. The Figure shows a TEM image with the beam direction parallel to the pore.
