Catalytic pyrolysis of biomass over CeO2 to prepare ketonic chemicals is an important way to achieve carbon emission reduction, whereas the role of catalyst structure has long been overlooked. In this work, nano-CeO2 with different crystal shapes, namely nanorods (R-CeO2), nano-polyhedra (P-CeO2), a...
