Anisotropic node distortions in amorphous MOFs: Low-valent Zr sites as catalytic hotspots

Berend Smit, Wendy Lee Queen, Emad Oveisi, Kumar Varoon Agrawal, Jian Hao, Till Marian Schertenleib, Beatriz Bueno Mouriño, Timo Markus Oskar Felder, Vikram Vinayak Karve, Andres Adolfo Ortega Guerrero

We introduce a new approach to defect engineering in Zr-based metal-organic frameworks (Zr-MOFs), aiming to reduce Zr site valency while preserving high node connectivity. Using a rapid heat treatment (RHT) in humid air, oxygen vacancies (O-vacancies) were ...
