Synthesis of Crystalline Mesoporous CdS Semiconductor Nanoarrays Through a Mesoporous SBA‐15 Silica Template Technique

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 [Cd 10 S 16 C 32 H 80 N 4 O 28 ]—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.
