Complete phenol removal in liquid-phase under moderate condition over Pt/CeO2–ZrO2–SnO2/ZrO2/SBA-16 catalysts

Abstract

Pt/CeO2–ZrO2–SnO2/ZrO2/SBA-16 catalysts were synthesized for the complete oxidation of phenol in liquid-phase under moderate condition. The loading of ZrO2 onto SBA-16 effectively enhanced the catalytic activity of Pt/CeO2–ZrO2–SnO2/ZrO2/SBA-16 due to the increase of the oxygen release and storage abilities of the CeO2–ZrO2–SnO2 promoter. Among the prepared catalysts with various ZrO2 loading amounts (0–36[Formula: see text]wt.%), the Pt(7[Formula: see text]wt.%)/Ce[Formula: see text]Zr[Formula: see text]Sn[Formula: see text]O2 (16[Formula: see text]wt.%)/ZrO2(24[Formula: see text]wt.%)/SBA-16 exhibited the highest activity, and the complete phenol removal was achieved after the reaction at 80∘C for 8[Formula: see text]h under the atmospheric pressure.
