     mesoporous cobalt-doped zns and zno nanoplates were fabricated by calcination of a zn0.95co0.05s(en)0.5complex (en = ethylenediamine), which was hydrothermally synthesized using ethylenediamine as a single solvent and chelating agent. when the as-prepared zn0.95co0.05s(en)0.5 complex was calcined, mesoporous nanoplates of wurtzite zn0.95co0.05s were formed, which then transformed to zn0.95co0.05o platelets upon further oxidation. photocatalytic performance of the as-prepared materials was investigated for decomposition of the azo dye (acid red 14) and photoelectrochemical current generation in aqueous na2s/na2so3 solution as probe reactions. the zn0.95co0.05s calcined at 500 °c exhibited the highest photocatalytic activity under uv irradiation and also showed the photocatalytic performance under visible light irradiation.
