Heterogeneous catalysis, a cornerstone of the industry, offers practical advantage easy recovery and multiple reuses, leading to significant process cost reduction. The catalytic activity porous materials, such as silica-based, zeolites, MOFs, has proven be not just interesting, but also superior conventional heterogeneous systems. In this paper, we highlight importance these their advances modifications through years, use catalysts or support for other materials enhance properties. Resumen....
In the present work, five MOF‐74 of Co, Cu, Mg, Ni and Zn synthesized at room temperature are evaluated as catalysts in aminolysis undissolved epoxides with styrene oxide cyclohexene oxide, former being much more reactive. All materials were stable after reaction, Cu‐, Mg‐ Zn‐MOF‐74 presented best catalytic activities TON values 95.8, 78.3 80.7 respectively a time 24 hours 60 °C, easy to recover wash for possible reuse these reactions.
MOF-74 is probably the MOF material that best combine three key features for catalytic applications: compositional versatility, presence of open metal sites and possibility becoming nanocrystalline, thus avoiding or minimizing any reactants/products diffusion problems within their pores. This work describes, first time, room-temperature preparation bimetallic nanocrystalline materials performance in solvent-free oxidation cyclohexene using oxygen as oxidant. Although oligo-metallic has been...
In the present work, nanocrystalline Zn-MOF-74 is shown to be a heterogeneous catalyst for acid-catalyzed ring-opening alcoholysis of cyclohexene oxide. The results corroborated that accessible open metal sites within material are critical conditions (Zn(ii) Lewis acid sites) this reaction. was tested at three different temperatures (30, 40, and 50 °C) Furthermore, oxide conversion 94% in less than two days. A comparison catalytic activity with crystal sizes homogenous phase, zinc acetate,...
Abstract Al 2 O 3 -TiO (AT) mixed oxide with atomic ratio Al/Ti = 25 and (A) supports were prepared by the sol-gel method impregnated to obtain monometallic Pd Pt (1 wt % of metal), bimetallic PdPt (Pd/Pt 4) catalysts. These catalysts tested in gas-phase hydrodechlorination 1,2 dichloroethane. The materials characterized nitrogen physisorption, X-ray diffraction analysis (XRD), temperature-programmed reduction (TPR) high-resolution transmission microscopy (HRTEM). AT support showed a BET...
