Crystalline POM@MOFs hybrids are very promising for catalysis, due to catalytically active polyoxometalates (POMs) dispersed at the molecular level, and enhanced stability of both POMs and metal-organic frameworks (MOFs). Herein, PW was encapsulated into MOF HKUST-1 through a facile liquid-assisted grinding method, and the obtained [Cu (BTC) (H O) ] [HPW O ] (BTC=1,2,3-benzenetricarboxylic acid) nanocrystals (NENU-3N) were applied as catalysts in the degradation of phenol. It is the first time that liquid-assisted grinding was applied in the preparation of nanocrystalline POM@MOFs hybrids. The NENU-3N nanocrystals catalyzed the degradation of phenol on the basis of both MOF and POM catalytic activities, representing the first example of POM@MOFs catalyst boosting catalytic oxidation reaction with double actives sites. Strikingly, up to 97 % conversion and 88 % mineralization have successfully realized by perfect cooperative catalysis between POMs and Cu nodes in MOFs at 35 °C. Moreover, comparative experiments suggest that the reduced size of NENU-3N catalyst is beneficial for improving its catalytic performance. Finally, the nanocrystalline NENU-3N catalyst possesses high stability, which can be easily recovered and reused 5 times without loss of catalytic activity.
The rapid emergence of drug-resistant bacteria has attracted great attention to exploring advanced antibacterial methods. However, single-modal antibacterial therapy is difficult to eliminate drug-resistant bacteria completely due to its low...
An arched dicadmium-substituted vanadogermanate dimer, {[Cd(en) 2 ][Cd(en)] 2 Ge 8 V 12 O 40 (OH) 8 } 2 {[Cd(en)(H 2 O)] 2 }·en· 2H 2 O (1; en = ethylenediamine), was prepared hydrothermally and characterized by IR spectroscopy, elemental analysis, powder X-ray diffraction, thermogravimetric analysis, UV/Vis diffuse reflectance spectroscopy, electrochemistry, and X-ray singlecrystal diffraction. Notably, 1 represents the first vanadogermanate-based dimer and contains two dicadmium-substituted [a]
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
