Abstract：

Nanosized　ZnNb2O6　photocatalysts　(band　gaps　̃4.0　eV)　were　successfully　synthesized　via　a　citrate　complex　method.　Their　particle　sizes　ranged　from　50　to　150　nm.　The　result　of　Mott-Schottky　measurement　revealed　that　the　flat-band　potential　of　ZnNb2O6　was　ca.　-1.3　V　versus　Ag/AgCl　at　pH　6.6.　The　photocatalytic　activities　of　the　samples　for　the　degradation　of　methyl　orange　were　evaluated　under　UV-light　(λ　=　254　nm).　It　was　found　that　the　sample　obtained　at　850°C　showed　the　highest　photocatalytic　activity　due　to　its　opportune　crystallinity　and　surface　area.　Furthermore,　OH　radicals　were　detected　as　the　major　oxidation　agents　responsible　for　the　decomposition　of　methyl　orange.　©　Springer　Science+Business　Media,　LLC　2011.
