Nanosized material tungstate zirconia (WO3/ZrO2) was prepared by surfactant -assisted precipitation. Structural characterizations of the catalyst were performed by N2adsorption– desorption and FTIR pyridine adsorption spectroscopy. Preparation of peracetic acid (PAA) from acetic acid (AA) and hydrogen peroxide (HP) under the catalysis of Lewis acid WO3/ZrO2was investigated.
