Among the wide assortment of zeolites based on aluminosilicates, Linde Type L (LTL) zeolite outstands as a support host owing to its porous framework and high adsorption surfaces. Thus, the incorporation of suitable guest molecules (fluorophores or metals) allows the development of photoactive and catalytic nanomaterials. In this chapter, we describe the design of materials based on LTL zeolite to achieve artificial antennae, inspired in the natural photosynthesis, and ecofriendly materials for the catalytic reforming of biogas. First, we describe the microwave-assisted synthesis of LTL zeolite with tunable size and morphology. Afterward, we test the energy transfer probability between the guest fluorophores into the LTL zeolite pores as the key process enabling the antenna behavior of this hybrid material with broadband absorption and tunable emission or predominant red fluorescence. Finally, we also test the behavior of LTL zeolite as a support material for the catalytic reforming of biogas. To this aim, suitable metals were impregnated onto LTL zeolite featuring different shapes and alkaline metal exchange. Activity tests indicated that diskand cylinder-shaped hosts were the most active ones, especially when bimetallic (Rh-Ni) catalysts were prepared. However, the alkaline metal exchange was ineffective to increase the hydrogen yield.
