Synthesis of UiO-66 based on ZrOCl2.8H2O and TiO2@UiO-66 Composite and photodegradation of Rhodamine-B

The organic-metal compounds are a new generation of Nano-adsorbents with high absorption capacity, due to the unique features, various methods of synthesis, the ability to adjust pore size, low density, high biocompatibility, high mechanical and thermal stability [1]. In this work, UiO-66 based on ZroCl2.8H2O was synthesized and its photocatalytic properties were investigated [2]. The use of the less acidic ZrOCl2·8H2O as the precursor seemed to be a suitable alternative to ZrCl4·xH2O, avoiding possible reproducibility issues as a consequence of the high hygroscopic character of ZrCl4. ZrOCl2·8H2O allowed the formation of good quality UiO-66 submicronic particles. In 70 minutes, UiO-66 destroyed 85% of Rhodamine-B under UV light irradiation
