PREPARATION OF METAL OXIDE BY USING DIRECT NANO-REPLICATION METHOD

摘要

The present invention is a direct nanopore replication method (direct nano-replication method) using nanoporous metal oxide catalysts relates to the manufacturing method, after impregnation and drying the precursor solution of the metal oxide nanoporous silica substance as a template wet the silica template - metal oxide made according to the method of the present invention for etching a regular nanoporous structure , because of the high specific surface area , obtain the excellent photocatalytic activity compared to traditional very useful catalyst for the adsorption and removal of organic and inorganic toxic substances .
