(Au nanorod)–(metal sulfide) core–shell structures are synthesized by employing Au nanorods as the starting reactants and metal thiobenzoates as the metal sulfide precursors in the presence of Ag + ions. The gas‐sensing property of the prepared (Au nanorod)–CdS sensor exhibit a significantly enhanced response and higher sensitivity in comparison with a CdS sensor.
