Abstract

The high-loaded (48-60 wt.%) 2-4 nm tetragonal ZrO₂ phase inserted in mesostructured silica SBA-15 by chemical solution decomposition (CSD) of Zr(n-PrO)₄ and activated at 873 K displayed ∼3 times higher capacity for surface sulfate ions and, respectively, 1.5-2.2 times higher catalytic activity per gram of SO₄-ZrO₂/SBA-15 composite in condensation of MeOH with t-BuOH and dehydration of isopropanol compared with the regular bulk sulfated zirconia material.
