METHOD FOR RECYCLING OF SILICA ETCHING WASTE AND METHOD FOR PREPARING MESOPOROUS MATERIALS

摘要

PURPOSE: A method for recycling silica etching waste and a method for manufacturing a meso-porous material are provided to reduce chemical waste and the use of chemical materials and to eco-friendly recycle silica etching waste. CONSTITUTION: Silica etching waste is generated from the silica etching process of a meso-porous carbon manufacturing process. The silica etching waste is used as the silica precursor of a meso-porous silica manufacturing process. The content of carbon in the silica etching waste is less than 0.3 weight%. A method for manufacturing the meso-porous silica includes the following: The silica etching waste is refined based on sonication and untrafine filter paper. The silica precursor is prepared. The silica precursor is introduced to micelle.
