Synthesis of mixed-metal MIL(Ti-Fe) from Vietnam ilmenite ore and its application for degradation of dye
In this work, the mixed-metal metal-organic frameworks MIL(Ti-Fe) were synthesized by the hydrothermal method. MIL(Ti-Fe) hybrid material was fabricated from ilmenite ore and 1,3,5-benzene tricarboxylic acid at a temperature of 130 oC for 24 hours. The prepared material was characterized by using scanning electron microscopy (SEM), X-ray diffra...

High acetone-sensing performance of bi-phase a-/g-Fe₂O₃ submicron flowers grown using an iron plate
Iron oxide nanostructures have been studied extensively because of their excellent magnetic, optical, electrical, and catalytic properties. This work introduces a simple process to synthesize directly bi-phase a-/g-Fe2O3 submicron flowers on a Fe foil in NH4OH. The flowers were assembled by using many nanoplates with an estimated thickness of 20...
