Sulfated zirconia has attracted great interest due to its robust acidity and high activities are realized in several important acid-catalyzed industrial reactions. However, its catalytically active structure has scarcely been understood so far due to the nonuniformity of its structure. Here, we successfully synthesized crystalline Zr₃SO₉ by hydrothermal synthesis. This material was comprised of a uniform structural arrangement including sulfate and exhibited outstanding catalytic activity for several acid reactions. Based on the crystal structure-catalytic activity relationship, acid catalysis over sulfated zirconia was clarified.
