TLDR
In this paper, an FTIR analysis of adsorbed CO and acetonitrile reveals the presence of Lewis and Bronsted sites in both catalysts, and the results indicate that the remarkable activity of SZ and FMSZ is not caused by exceptionally strong acid sites, but by stabilization of the transition state complex at the surface.About:

TL;DR: This material has a Hammett acidity function H0 ≤ -14.5 and is thus identified as a superacid, providing the first evidence for superacidity in MOFs, attributed to the presence of zirconium-bound sulfate groups structurally characterized using single-crystal X-ray diffraction analysis.
