A Method for the Cost-Effective Preparation of Organofunctional, Mesostructure Molecular Sieves for Toxic, Heavy Metal Ion Trapping and Heterogeneous Catalysis

IntroductionThe ability to create lower cost, industrial strength catalytic materials with desired pore sizes and with a chemically modified surface of organic groups can improve efficiency and selectivity in existing industrial processes that modify vast volumes of fluid. Template agents (usually organic molecules or ions) direct the crystallization...
