Abstract
The present invention provides methods for preparing hydrothermally stable MCM-41 mesoporous molecular sieves incorporating aluminum and other transition metals. The materials prepared by these methods possess a very high surface area and narrow uniform pore distribution in the mesopore region, and are highly thermally stable whereby the ions are not leached out after high temperature annealing.
