One-pot synthesis of ordered mesoporous Cu-KIT-6 and its improved catalytic behavior for the epoxidation of styrene: Effects of the pH value of the initial gel

Using a synthesis solution at a pH of 3.78, approximately 4.6% Cu2+ was incorporated into the framework of a KIT-6 support in the form of -Cu-O-Si- groups. Enhanced selectivity for styrene oxide was obtained over this Cu-KIT-63.78 catalyst.
