Alumina-supported bimetal oxide (PdRuOx) catalysts were prepared by galvanic displacement reduction method for partial oxidation of methane into HCHO, and evaluated in a fixed-bed reactor at relatively low temperatures of 280-310 ºC, using O₂ as the oxidant. The bimetal oxide catalysts exhibited high selectivity to HCHO. Characterizations results showed that bimetal oxide-PdRuOx species with Pd-(O)-Ru active sites can selectively convert CH₄ to HCHO through the transfer of its novel lattice oxygen. And in this process, CH₃OH may play as an intermediate.
