The new nanocomposites, Pd/C/ZrO2, PdO/ZrO2, and Pd/PdO/ZrO2, were prepared by thermal conversion of Pd@UiO-66-Zr−NH2 (MOF) in nitrogen or air atmosphere. The presence of Pd nanoparticles, uniformly distributed on the ZrO2 or C/ZrO2 matrix, was evidenced by transmission electron microscopy, scanning electron microscopy (SEM), Raman and X-ray Photoelectron Spectroscopy (XPS) methods. All pyrolysed composites retained the shape of the MOF template. They catalyze carbonylative Suzuki coupling under 1 atm CO with an efficiency significantly higher than the original Pd@UiO-66-Zr−NH2. The most active PdO/ZrO2 composite, formed benzophenone with TOF up to 1600 h−1, while by using Pd@UiO-66-Zr−NH2, much lower TOF values, 51–95 h−1, were achieved. After the reaction, PdO/ZrO2 was recovered with the same composition and catalytic activity. Very good results were also obtained in the transfer hydrogenation of benzophenones to alcohols with Pd/C/ZrO2 and PdO/ZrO2 catalysts under microwave irradiation. 相似文献

Photostability of an antidepressant agomelatine under the simulated solar radiation was studied. Quantitative and qualitative analysis of this process was performed with the use of UHPLC-DAD system coupled with a high resolution hybrid ESI-Q-TOF mass spectrometer. In contrast to the foregoing studies agomelatine turned out to be relatively photolabile compound. During the experiment six transformation products were formed, and their structures were elucidated on the basis of MS/MS fragmentation spectra. Four of these photoproducts were found to be a result of aromatic and aliphatic hydroxylation. Additionally, identified products were submitted to the in silico toxicity evaluation, which showed that some of them could be more mutagenic or toxic to rodents than the parent compound. 相似文献
