SBA-15 synthesis from sodium silicate prepared with sand and sodium hydroxide
Materials Research Express, 2020 In the industry, sodium carbonate is used to prepare sodium silicate; however, this process generates great volumes of CO _2 . In this work, sodium hydroxide has been proposed to prepare sodium silicate using natural sand. Two experimental variables were
