Abstract

BaTi_1-xSn_xO₃-supported Ni-based catalysts recovered from spent Ni-metal-hydride (Ni-MH) batteries [wNi/BaTi_1-xSn_xO₃ (x = 0.0, 0.2, 0.4, 0.6, and 1.0)] were prepared. Their catalytic activities for model biogas reforming reactions were examined at 800 °C and compared with that of wNi/γ-Al₂O₃. According to the results, wNi/BaTi_0.8Sn_0.2O₃ exhibited high reforming performance and high sustainability among the catalysts tested. wNi/γ-Al₂O₃ exhibited unsustainability due to carbon deposition, although its performance was excellent for a short time. BaTi_0.8Sn_0.2O₃ functioned as an inhibitor, depressing carbon deposition. This function was likely due to the mobile oxide ions and alkaline earth oxides in the catalyst supports.
