Abstract Seven TiO2 morphologies were synthesized and evaluated for photocatalytic oxidation (PCO) of methyl ethyl ketone (MEK) in air. Photocatalysts were fabricated via hydrothermal method and the preparation parameters were adjusted to keep the variations in photocatalysts’ crystallinity, crystal composition, and surface area in narrow ranges, thus, allowing a better understanding of the morphology-performance relationship. Based on the characterization results and data available in literature, possible morphological evolutions for different structures were put forward. MEK removal efficiency improved in the order of solid spheres
