Abstract
Synthetic methods for making an all-silica MCM-41 mesoporous silicate of high long-range order are reported. The product shows up to seven o rders of X-ray diffraction and good stability under calcination condit ions. The greatest improvement in structure occurs when the pH is held between 9 and 10 during synthesis and the sulfate anion is present.
