نویسندگان
چکیده
Catalytic degradation of tartrazine in the presence Oxone? activated by a catalyst constituted cobalt supported on nanocomposite smectite with chitosan-derived carbon was investigated. The synthesized using impregnation followed carbonization at 773 K an inert atmosphere. previously fully characterized appropriate characterization methods, including XRPD, XPS, FTIR, HR-TEM, and low-temperature N2-physisorption analysis. catalytic experiments were performed varying different experimental parameters (dye concentration, temperature, initial pH reaction solution). kinetic thermodynamic estimated from results. kinetics data showed best fit pseudo-first-order model. activation energy investigated process calculated according to Arrhenius equation. excellent performance low temperatures even 298 K, wide range values.

متن کاملEnhancement in the reducibility of cobalt oxides on a mesoporous silica supported cobalt catalyst.
The silylation of SBA-15 enhances the reducibility of cobalt oxides on a SBA-15 supported cobalt catalyst, and consequently increases the catalytic activity for Fischer-Tropsch synthesis of hydrocarbons from syngas and selectivity for longer chain products.
متن کاملEfficient elimination of caffeine from water using Oxone activated by a magnetic and recyclable cobalt/carbon nanocomposite derived from ZIF-67.
To eliminate caffeine, one of the most common pharmaceuticals and personal care products, from water, Oxone (peroxymonosulfate salt) was proposed to degrade it. To accelerate the generation of sulfate radicals from Oxone, a magnetic cobalt/carbon nanocomposite (CCN) was prepared from a one-step carbonization of a cobalt-based Zeolitic Imidazolate Framework (ZIF-67). The resultant CCN exhibits i...
