Design, synthesis, and applications
CUCAM – is a Centre of Excellence focused on research in advanced materials. It has been established under the Chemistry Section at the Faculty of Science based on a support from Ministry of Education, Youth and Sports (OP VVV “Excellent Research Teams”, project No. CZ.02.1.01/0.0/0.0/15_003/0000417).
a world-leading Centre of Excellence in Advanced Materials located at Charles University (CU) in Prague, specialising in the Design, Synthesis and Application.
is on the use of modular (i.e. low dimensional) building units for the preparation of new advanced materials, with a particular emphasis on the preparation of hybrid solids.
is to overturn the conventional thinking and practice in materials science by developing methodologies that can target ‘unfeasible’ materials – that is, materials which cannot be prepared by traditional methods.
open up routes to materials that have different properties (both chemical and topological) to those we currently have, which in turn opens up new avenues for exploitation.
The goal is to develop the science and the human capital at Charles University, positioning the Centre at the forefront of this field and building an international network of collaborators and partners that cements the position of the research as a globally recognized brand. An important aspect of this is to develop the capacity of the researchers to develop industrial and commercial links to exploit novel and inventive research findings.
Strategy
We work on creative and innovative chemistry that impacts across a wide range of different areas of science and technology.
Our particular focus is in advanced materials, but we are looking outwards to cross borders between scientific fields.
We are building and leading strong networks of scientists that transcend the traditional boundaries.
The key scientific advances
● The development of new chemistry concepts that will allow step changes in exploitation of the outstanding properties of advanced materials in a way that has not been possible previously.
● The development of generalised synthetic strategies to target novel properties, and subsequent demonstration of these properties.
● The use of world-leading characterisation and computational techniques to connect novel chemistry to new properties through transformative synthetic chemistry, structural characterisation and computational prediction and simulation.

Aluminosilicate zeolites are traditionally used in high-temperature applications at low water vapour pressures, such as heterogeneous catalysis and gas separation, where the zeolite framework is generally considered to be stable and static. Increasingly, zeolites are being considered for applications under milder aqueous conditions, in emerging fields such as biomass conversion, low temperature oxidation catalysis and medicine. However, it has not yet been established how neutral liquid water at mild conditions affects the stability of the zeolite framework. Here, we show that covalent bonds in the zeolite chabazite (CHA) are labile when in contact with neutral liquid water, which leads to partial but fully reversible hydrolysis without framework degradation. We present ab initio calculations that predict novel, energetically viable reaction mechanisms by which Al-O and Si-O bonds rapidly and reversibly break at 300 K. By means of solid-state NMR, we confirm this prediction, demonstrating that isotopic substitution of 17O in the zeolitic framework occurs at room temperature in less than one hour of contact with enriched water. The framework is found to heal, with no long-timescale degradation of the framework over at least 200 days. The observation that zeolites are dynamic entities under mild aqueous conditions, with fast breaking of the framework, challenges the conventional view of these materials as static and inert. Considering the industrial importance of zeolites and their growing applications under mild conditions, these findings will be of great importance.

Porous solids containing internal pores with sizes ranging from angstroms to nanometers are highly useful and valuable in the catalysis, separation, and storage of molecules because these materials provide large surface areas and void spaces for the interaction and adsorption of molecules. In particular, two-dimensional zeolites (2D, sometimes called layered zeolites) with layer thickness of 2–3 nm (1–2 unit cells) have enabled the synthesis of advanced materials and their application in catalysis for the transformation of bulky substrates unable to enter zeolite pores, thereby substantially increasing the number of zeolite applications and modifications. Accordingly, this Review aims to highlight recent developments in the synthesis, characterization, and application of 2D zeolites, focusing on the two most important representatives, MWW and MFI.
Researchers from the Department of Physical and Macromolecular Chemistry (Valeryia Kasneryk, Mariya Shamzhy, Qiudi Yue, Michal Mazur, Russell E. Morris, Jiří Čejka and Maksym Opanasenko), in collaboration with colleagues from the University of Science and Technology of China and ShanghaiTech University developed a new synthesis strategy for transformation of “openwork” zeolites into materials with new topologies at room temperature. This breakthrough discovery provides a way forward towards engineering nanoporous materials and increasing the number of zeolites available for future applications.
Zeolites are crystalline porous materials used in gas separation and catalysis. Although millions of thermodynamically stable structures have been predicted, until now, the zeolite community has only recognized approximately 250 different zeolite topologies. Such discrepancy between the numbers of proposed zeolite topologies and those prepared via traditional hydrothermal approaches has prompted the development of alternative strategies for zeolite synthesis, in particular ADOR (Assembly-Disassembly-Organization-Reassembly). ADOR is a unique approach because the topology of new zeolites can be easily predicted based on the parent structure. However, attempts to transform fragile structures (for example, zeolite of IWW structural type) using this approach have been unsuccessful thus far. Yet, these researchers from the Department of Physical and Macromolecular Chemistry developed a straightforward strategy to construct new zeolites through non-contact vapour-phase-transport rearrangement. This method offers the opportunity to prepare new zeolite topologies otherwise inaccessible by both hydrothermal and conventional ADOR synthesis routes. In addition, combining in situ diffraction and X-ray absorption spectroscopy makes it possible to follow the mechanism of the rearrangement process and to describe intermediate structures. The successful application of vapour-phase-transport rearrangement to zeolites of different topologies highlights therefore the potential of this technique for 3D-to-3D transformations of crystalline materials with labile frameworks collapsing upon contact with the solvent. Moreover, in combination with other methods for post-synthesis alteration of 3D frameworks, this approach enables the manipulation of the structures of anisotropically labile materials.
