I am thrilled to announce the culmination of a journey spanning more than 30 years. The quest to extend the pore size of zeolites beyond the conventional 12-membered ring, with pore openings slightly larger than 0.7 nm, began in the 1980s. While aluminophosphates and ordered mesoporous silica materials with larger pores were developed, they could not match the robustness and strong acidity of aluminosilicate zeolites. Today, we report the synthesis of the first intrinsically mesoporous aluminosilicate zeolite, ZMQ-1. This groundbreaking material features 28-membered ring pore channels (2.3 x 1.2 nm) interconnected by 10-membered rings. With a tunable Si/Al ratio (15–100), exceptional (hydro)thermal stability (up to 800°C), a substantial pore volume (0.47 cm³/g), and a high specific surface area (1447 m²/g), ZMQ-1 represents a significant advancement. ZMQ-1 is the inaugural member of a new class of zeolitic materials, opening new horizons for process industries thanks to its intrinsic mesoporosity, robust framework, and inherent acidity. This discovery not only redefines the potential of zeolitic materials but also inspires the development of other stable mesoporous zeolites. Nature, December 11, 2024 https://lnkd.in/d7xkv_9U
Numbers are huge, for instance SA 1447 m2/g is relatively high compared to present day typical FCC catalyst. How this SA is distributed will be interesting understand.
Exceptional ! Well done to your team Valentin. I tried many times during my PhD thesis to realise such achievement but never succeeded. What ZMQ stands for ?
Applications to zeolite chemistry in heavy oil processing now beckons ...
Again and again, as when I started to cognize the crystal structures.... For me it's always about beauty, behind the estimations e.g. crystal structure refinement. So beautiful! Congratulations!
Congratulations Valentin Valtchev for this big achievement. The article is very informative. I hope, in future, we may synthesize ZMQ-1 from fly ashes to make this process more sustainable. Waiting for more good news about ZMQ-1 potential applications.
This material offers new opportunities for most traditional petrochemical processes. A major advance in microporous materials. Congratulations.
very nice work! this opens a new perspective for catalyses and adsorbtion on larger molecules.
Would this imprive its selectivity in cracking reactions ?
Why do this?
