Zeolites hold a key position as heterogeneous catalysts and adsorbents due to their high surface area, molecular sieving effect, and versatility in chemical composition and structural topology. However, the hydrothermal synthesis process traditionally employed for their preparation is complex and not yet fully understood. This complexity renders challenging the precise tailoring of essential properties, such as structural topology or the type and location of active sites. Achieving control over these features is highly sought after, not only from an academic perspective but also for industrial applications. The ADOR method exploits labile domains within the zeolite framework to dismantle the parent structure and reconstruct it in a controlled manner. Classical ADOR has been shown to produce a wide range of materials with well-defined pore sizes and structural topologies. Nonetheless, the incorporation of active species into specific framework positions or the precise control of their local environment remains challenging due to the interplay of complex phenomena and the narrow range of conditions required for successful implementation. This project seeks to employ germanosilicate zeolites as precursors and building blocks for the development of novel zeolite and zeolite-derived materials with unique properties, such as odd-member rings or precisely located active sites.
