Method for preparing rare earth metal catalysts with honeycomb- like alloy supports and catalysts obtained thereby

摘要

This invention relates to a method for preparing rare earth metal catalysts with a honeycomb-like alloy support and catalysts obtained thereby, which method comprises: preparing a corrugated, perforated metal alloy support tape, coating the support tape with a solution of a mixture of light rare earth metal salts; drying the support tapes; decomposing and oxidizing the rare earth metal salts into catalytic materials having a perovskite or a spinel type crystal structure.
