Synthesis of Nitride Zeolites in a Hot Isostatic Press

Abstract

The recently introduced nitridophosphate synthesis in a hot isostatic press (HIP) enabled simple access to large‐scale product quantities starting from exclusively commercially available starting materials. Herein, we show that this method is suitable for the synthesis of highly condensed functional nitridophosphates, as well. Hence, the syntheses of the nitridophosphate zeolites Ba3P5N10X (X=Cl, Br) are presented as proof of concept for this innovative access. Furthermore, samples of unprecedented Sr3P5N10X (X=Cl, Br) were prepared and characterized to demonstrate the advantages of this synthetic approach over commonly used methods. Luminescence investigations on Eu2+‐doped samples of AE3P5N10X (AE=Sr, Ba; X=Cl, Br) were carried out and characteristics of observed emission bands are discussed.

“…Zeolites are microporous aluminosilicates constructed by connecting the corner sharing TO 4 tetrahedra (T = Si, Al), [1][2][3] the commercial relevance of which is being demonstrated by a wide range of practical applications such as catalysis, adsorption, ion-exchange, selective separation, etc., [4][5][6][7] owing to their overwhelming advantages including the abundant micropores of molecular dimensions, ion-exchanging ability, tunable morphology and size, and high stability, to name a few. 8,9 Recent advances made in materials community highlight that zeolites can be promising host materials or starting materials for developing luminescent materials through the insertion of luminescent centers within the micropores of zeolites.…”
