A novel crystalline mesoporous CdS semiconductor (see Figure) has been synthesized with the aid of a mesoporous silica template through a simple single precursor decomposition route at low temperature. The precursor used—cadmium thioglycolate [Cd10S16C32H80 N4O28]—is not only the Cd but also the S source. The resultant CdS material is an inverse replica of the silica template and retains its mesostructured order.
