Cerium-doped zirconium-based NH2-UiO-66 nanoparticles were synthesized in ionic liquid 1-butyl-3-methyl- imidazolium acetate at room temperature. The crystal structure and morphology were studied using X-ray diffraction, infrared spectroscopy, scanning electron microscopy and transmission electron microscopy. The valence state and distribution of elements in the obtained materials were examined using X-ray photoelectron spectroscopy and energy-dispersive X-ray spectroscopy. Catalytic performance studies show that the cerium-doped NH2-UiO-66 exhibits improved catalytic efficiency in the cycloaddition reaction of 1,2-butylene oxide and carbon dioxide than pure NH2-UiO-66. Studies on the photoelectric properties indicate that the cerium-doped NH2-UiO-66 catalyst possesses strong photocurrent response, low interfacial charge transfer resistance, narrow band gap, and low flat band potential. This work provides a new approach of synthesizing high-performance catalyst for photocatalytic CO2 cycloaddition.
