The current study examined the effect of metal oxide catalysts on the sorption and photocatalytic efficiencies for the removal of ciprofloxacin and ofloxacin in water. ZnO and TiO2 catalysts are prepared using a suitable method based on the sol-gel process, which have a great change in structural and textural properties. The structure and surface area of the synthesized catalysts wer...

The synthesis of two-dimensional double metal cyanide complexes of the formula Co(H2O)2[M(CN)4].4H2O (M=Ni, Pd or Pt) and the X-ray crystal structure of Co(H2O)2[Pd(CN)4].4H2O are presented. The anhydrous forms of these complexes were found to be effective catalyst precursors for the homopolymerization of propylene oxide as well as the random copolymerization of propylene oxide and carbon dioxi...

Strain promoted cycloaddition is presented as a tool for RNA conjugation on the solid phase; RNA-cyclooctyne conjugates are prepared by cycloaddition to both azide (strain-promoted azide-alkyne cycloaddition, SPAAC) and nitrile oxide dipoles (strain-promoted nitrile oxide-alkyne cycloaddition, SPNOAC). The conjugation is compatible with 2'-OMe blocks and with 2'-O-TBDMS protection on the ribose...

Metal-incorporated SAPO-34 catalysts were prepared by one-step hydrothermal method. Effects of various parameters including the types metal ions, Cu2+ sources, structure directing agents (SDAs), temperature and time on catalyst activity metal-incorporated investigated. Three (Cu/SAPO-34, Fe/SAPO-34 Mn/SAPO-34) successfully obtained. Compared with Mn/SAPO-34 catalysts, Cu/SAPO-34 revealed comple...

The effect of vanadium oxide as support and promoter on supported rhodium catalysts on the CO hydrogenation has been investigated at 0.15 and 4.0 MPa. Rh/V,O, reduced at 723 K has a good selectivity toward oxygenated products, especially C,-oxygenates, but has a low activity added as a promoter to catalysts consisting and stability. Vanadium oxide of rhodium supported on silica and alumina show...

In this paper, the effect of nanocatalytic metal-organic framework based on copper metal and bis-tetrazolamine (CuBTA) ligand functionalized with cobalt (II) oxide nanoparticles on the thermal decomposition behavior of ammonium perchlorate (AP), using differential survey calorimetry (DSC) has been reviewed. First, the metal-organic framework (CuBTA) was synthesized from the raw materials of cop...

Solar-to-fuel energy conversion relies on the invention of efficient catalysts enabling water oxidation through low-energy pathways. Our aerobic life is based on this strategy, mastered by the natural Photosystem II enzyme, using a tetranuclear Mn-oxo complex as oxygen evolving center. Within artificial devices, water can be oxidized efficiently on tailored metal-oxide surfaces such as RuO2. Th...

Conventional supported Pt catalysts have often been prepared by loading Pt onto commercial supports, such as SiO2, TiO2, Al2O3, and carbon. These catalysts usually have simple metal-support (i.e., Pt-SiO2) interfaces. To tune the catalytic performance of supported Pt catalysts, it is desirable to modify the metal-support interfaces by incorporating an oxide additive into the catalyst formula. H...

The mechanistic connections among propane oxidative dehydrogenation (ODH) rates, H2 reduction rates, and the electronic transitions responsible for the absorption edge in the electronic spectra of dispersed metal oxides were explored for VOx, MoOx, WOx, and NbOx samples consisting predominately of two-dimensional oxide domains supported on Al2O3, ZrO2, and MgO. For a given active oxide, propane...
