Se/ZrO2 can be prepared via the reaction of readily available zirconia with NaHSe. The material can catalyze the oxidation of phenol to prepare p-benzoquinone. Compared with traditional selenium-catalyzed oxidation reactions, this reaction does not require the use of chemical oxidants, but can directly utilize molecular oxygen as the oxidant, significantly reducing synthesis costs and being relatively safe. Se/ZrO2 is a stable selenium-containing material that can be recycled and reused for multiple times without deactivation. Its excellent catalytic oxidation performance is expected to be used in industry.

Key words: selenium, zirconia, catalyzed oxidation, phenol, p-benzoquinone
