Morphology and crystal-plane effects of Zr-doped CeO2 nanocrystals on the epoxidation of styrene with tert-butylhydroperoxide as the oxidant

120Zr-doped CeO2 catalysts with different morphologies catalyzing styrene oxidation were investigated and Zr-doped CeO2 nanorods exhibited the highest catalytic performance according to the highest Ce3+ content and oxygen vacancies.
