Hydrothermally synthesized Ti/Zr bimetallic MOFs derived N self-doped TiO2/ZrO2 composite catalysts with enhanced photocatalytic degradation of methylene blue

The nitrogen-rich Ti/Zr bimetallic metal organic framework (MOF) precursors were synthesized by a facile one-step hydrothermal method. By pyrolyzing the MOF precursors at 600 °C, the N self-doped TiO2/ZrO2 composites were obtained, and the morphology of the MOF precursor was well preserved. The powder X-ray diffraction (XRD) patterns and transmission electron microscopy (TEM) indicated the highly crystalline polycrystallization of mix-phase TiO2...
