t -ZrO 2 prepared by a novel zirconium oxalate synthesised solvothermally

In this work, the authors intentionally employ the oxalic acid (OA) to replace terephthalic acid to synthesise a novel zirconium oxalate under the similar reaction condition with UIO-66. The powder X-ray diffraction and thermal gravimetric analysis confirm that as-synthesised zirconium oxalate is a pure phase and oxalate serves as bridging ligand. Scanning electron microscope indicates that zircon...
