| titleOfInvention | A method for preparing porous cerium oxide-copper oxide composite material by chemical etching |
| abstract | The invention discloses a method for preparing a porous cerium oxide-copper oxide (CeO 2 -CuO) composite material by a chemical corrosion method. First, dissolve the salt containing cerium ions, copper ions, zinc or aluminum ions in pure water in a certain proportion, and add a certain proportion of surfactant; then, drop the precipitant under stirring conditions to obtain the precipitate, the solution pH The value is kept between 8-10; add an appropriate amount of reducing agent and continue to stir for a certain period of time, separate and clean the precipitate, dry and calcinate at high temperature to obtain the oxide precursor; finally, fully corrode with an alkaline etchant to dissolve part of the oxide, Cerium oxide and copper elements are retained, separated, cleaned, dried and heat-treated at high temperature to obtain a nanoporous cerium oxide-copper oxide composite material. The invention has the advantages of simple operation, no need for special equipment, suitable for batch preparation, etc., and the composition and microstructure of the prepared porous cerium oxide-copper oxide composite material can be adjusted, and has better catalytic activity. |
