A method for preparing rare earth metal catalysts with honycomb-like alloy as supports and the catalysts obtained thereby

摘要

This invention relates to a method for preparing rare earth metal catalysts with a honeycomb-like alloy as support and catalysts obtained thereby, which method comprises the following steps: coating a solution of mixture of rare earth metal salts onto the surfaces of support tapes; drying said support tapes quickly; decomposing said rare earth metal salts; and oxidizing the rare earth metals into catalytic materials having the desired chemical structures.
