%X <b>  </b>Bi-metallic Pt-Pd catalytic films were immobilized on Nafion-117 membrane to decompose hydrogen peroxide. A basic medium helps to enhance autocatalysis of hydrogen peroxide decomposition reaction. Although H<SUB>2</SUB>O<SUB>2</SUB> decomposition is strongly increased by the presence of iodide ions and sodium dodecyl sulfate species but they deactivate the catalytic surface. Among several sulfate salts (CoSO<SUB>4</SUB>.7H<SUB>2</SUB>O, K<SUB>2</SUB>SO<SUB>4</SUB> and CuSO<SUB>4</SUB>), only NiSO<SUB>4</SUB>.7H<SUB>2</SUB>O influenced to increase the reaction rate. Meanwhile, the Hg<SUP>2+</SUP> species not only inhibits the decomposition process but also permanently damage the activity of the catalytic surface
