Polyoxometalates based organic–inorganic nanohybrids. Synthesis, characterization and catalytic application of CeIV sandwich and Preyssler-type polyoxometalates hybrids
Organic–inorganic hybrids were successfully synthesized by a simple ion self-assembly (ISA) method of H2[P2W18Ce3(H2O)2O71]10− (PWCe), and [Na(H2O)P5W30O110]14− (P5W30) polyoxometalates with p-Phenylenediamine (PPD). The nanohybrids and their products obtained by calcination (400 °C, 2 h) were characterized by FTIR, XRD, SEM/EDS, DTGA and BET analysis. The catalytic efficiency of organic–inorganic nanohybrids were examined in degradation of some synthetic pollutants. The results showed that the PWCe based nanohybrids have very much efficiency toward degradation of synthetic pollutants compared of P5W30 based nanohybrids. Of these, the results confirmed that snowball PWCe nanocompposite obtained by calcination show even more efficiency. It was unveiled that snowball PWCe nanocomposite exhibited an outstanding catalytic activity higher than 90.0% MB, RhB, CR, EBT and 75.0% TC degradation efficiency within 12−40 min. Further investigations revealed that, the structure of the polyoxometalates, PWCe and P5W30 have changed due to calcination and tissue quality of nanohybrids has improved.
期刊介绍:
The primary objective of the Journal of Sol-Gel Science and Technology (JSST), the official journal of the International Sol-Gel Society, is to provide an international forum for the dissemination of scientific, technological, and general knowledge about materials processed by chemical nanotechnologies known as the "sol-gel" process. The materials of interest include gels, gel-derived glasses, ceramics in form of nano- and micro-powders, bulk, fibres, thin films and coatings as well as more recent materials such as hybrid organic-inorganic materials and composites. Such materials exhibit a wide range of optical, electronic, magnetic, chemical, environmental, and biomedical properties and functionalities. Methods for producing sol-gel-derived materials and the industrial uses of these materials are also of great interest.
