Abstract

Single-crystalline La_0.6Sr_0.4MnO_3+δ microcubes of cubic perovskite phase were prepared hydrothermally. The adopted temperature and time of hydrothermal treatment and the amount of KOH used had great effects on the low-temperature reducibility of La_0.6Sr _0.4MnO_3+δ . The initial H₂ consumption rate of La_0.6Sr_0.4MnO_3+δ played a vital role in determining its catalytic activity for toluene combustion. It is concluded that the perovskite-type oxide catalyst with a higher initial H ₂ consumption rate displayed a higher catalytic activity for the addressed reaction.
