“…Pd‐HTs were synthesized by using a previously described mesoscale continuous‐flow method (Figure S1 in the Supporting Information), which yielded materials with reproducible elemental composition, surface area, and acid–base properties. Four Pd‐HT catalysts ( A , B , C , and D ) were synthesized with nominal loadings of 5, 1, 0.5, and 0.1 mol % Pd, respectively, by varying the metal precursor concentrations (Table S1 in the Supporting Information).…”
