Machine learning (ML), when used synergistically with atomistic simulations, has recently emerged as a powerful tool for accelerated catalyst discovery. However, the application of these techniques has been limited by the lack of interpretable and transferable ML models. In this work, we propose a curriculum-based training (CBT) philosophy to …

This work describes the synthesis of zeolite Na-P 1 using a kaolinitic rock. Appearance of Na-P 1 phase begins at about 24 h at 65 °C and at about 8 h at 100 °C. The existence field of the Li-A (BW) zeolite is very large, in fact no phase replaces the zeolite in the time interval 1–91 h at 65 °C and 1–54 h at 100 °C.

Zeolite A is the first commercialized synthetic zeolite, and it is used widely as a water softener in laundry detergents . The structure of zeolite A is shown in Fig. 1(b) ; it consists of sodalite cages that are connected by bonds between their four-membered rings to form a 3D network with ≈1.14 nm diameter supercages interconnected by ≈0 ...

Animation (above): Ion exchange in zeolites: the zeolite "cage" (gray) traps incoming ions (red and orange) and releases others (yellow) in their place. The most interesting thing about zeolites is their open, cage-like, "framework" structure and the way it can trap other molecules inside it. This is how water molecules and alkali or alkaline ...

Conventional methods for characterizing zeolites, like X-ray diffraction (XRD), infrared (IR), UV-vis spectroscopy, Raman spectroscopy and nuclear magnetic resonance (NMR), were first applied to study zeolite materials from the 1950s to 1980s and were the basis of the discovery of the unique and fascinating properties of the zeolite …

This is perhaps not surprising given that Raman spectroscopy can be sensitive to collective, non-polar vibrations such as those of silica-based rings. This zeolite Raman assignment approach arises from observed correlations between known rings in zeolites and the locations of Raman bands. For example, zeolites with so-called "four …
