Abstract

AbstractWe report a novel strategy to prepare supported Pd catalysts for low‐temperature methane combustion. The structure–property relationship of the catalysts was investigated by tuning the shape and crystal planes of supporting Co3O4 nanocrystals. Pd/Co3O4 nanosheets are more reactive than Pd/Co3O4 nanobelts and nanocubes with the same Pd loading. The strong surface interaction between the Co3O4 unit cell and the PdO unit cell on {112} crystal plane of Pd/Co3O4 nanosheets has been analyzed by using high resolution transmission electron microscopy and temperature programmed reduction experiments.
