A　new　strategy　for　the　construction　of　a　sensitive　and　stable　electrochemiluminescent　platform　based　on　titanate　nanotubes　(TNTs)　and　Nafion　composite　modified　electrode　for　luminol　is　described,　TNTs　contained　composite　modified　electrodes　that　showed　some　photocatalytic　activity　toward　luminol　electrochemiluminescence　emission,　and　thus　could　dramatically　enhance　luminol　light　emission.　This　extremely　sensitive　and　stable　platform　allowed　a　decrease　of　the　experiment　electrochemiluminescence　luminol　reagent.　In　addition,　in　luminol　solution　at　low　concentrations,　we　compared　the　capabilities　of　a　bare　glassy　carbon　electrode　with　the　TNT　composite　modified　electrode　for　hydrogen　peroxide　detection.　The　results　indicated　that　compared　with　glassy　carbon　electrode　this　platform　was　extraordinarily　sensitive　to　hydrogen　peroxide.　Therefore,　by　combining　with　an　appropriate　enzymatic　reaction,　this　platform　would　be　a　sensitive　matrix　for　many　biomolecules.　Copyright　©　2013　John　Wiley　&　Sons,　Ltd.　Copyright　©　2013　John　Wiley　&　Sons,　Ltd.
