摘要: Germanosilicates, an important family of zeolites with increasing number members and attractive porosities, but containing a large quantity unstable Ge atoms in the framework, meet great obstacles terms limited thermal hydrothermal stability when it comes to practical use. A facile stabilization method thus has been developed substitute isomorphously for Si atoms, giving rise ultrastable siliceous analogues pristine germanosilicates.
