A new strategy to improve catalytic activity for chlorinated volatile organic compounds oxidation over cobalt oxide: Introduction of strontium carbonate

, (2021)

Co3O4–SrCO3 catalysts with various Sr/Co ratios were synthesized by the coprecipitation method, and their properties were tuned by adjusting the Sr/Co molar ratio. Furthermore, the catalytic combustion of vinyl chloride (VC) was used to evaluate the catalytic activity of the Co3O4–SrCO3 catalysts. The physicochemical properties of the catalysts were studied by X-ray diffraction (XRD), infrared spectroscopy (IR), N2 sorption, scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), H2 temperature-programmed reduction (H2-TPR) and VC temperature-programmed desorption (VC-TPD). The results showed that the Co3O4–SrCO3 catalysts exhibited composite phases of Co3O4 and SrCO3 and the presence of interactions between them. As a result, the crystallization of the Co3O4 phase for the Co3O4–SrCO3 catalysts was restrained, and the state of Co on the catalyst surface was adjusted. Furthermore, the reducibility and VC adsorption capacity of the Co3O4–SrCO3 catalysts with Sr/Co molar ratios of 0.2 and 0.4 were enhanced compared with those of the Co3O4 catalyst. Otherwise, catalyst SrCo-0.4 exhibited excellent catalytic performance, accompanied by the highest reaction rate and the lowest apparent activation energy. More importantly, the optimized SrCO3–Co3O4 catalyst showed superior catalytic performance compared with other transition metal oxides in previous literature. These results brought a new idea for promoting the activity of transition metal catalysts for the deep oxidation of chlorinated volatile organic compounds (CVOCs) by introducing alkaline-earth metal salts.

Onion-Like Graphene Carbon Nanospheres as Stable Catalysts for Carbon Monoxide and Methane Chlorination

Centi, Gabriele,Barbera, Katia,Perathoner, Siglinda,Gupta, Navneet K.,Ember, Erika E.,Lercher, Johannes A.

, p. 3036 - 3046 (2015)

Thermal treatment induces a modification in the nanostructure of carbon nanospheres that generates ordered hemi-fullerene-type graphene shells arranged in a concentric onion-type structure. The catalytic reactivity of these structures is studied in comparison with that of the parent carbon material. The change in the surface reactivity induced by the transformation of the nanostructure, characterized by TEM, XRD, X-ray photoelectron spectroscopy (XPS), Raman, and porosity measurements, is investigated by multipulses of Cl2 in inert gas or in the presence of CH4 or CO. The strained C-C bonds (sp2-type) in the hemi-fullerene-type graphene shells induce unusually strong, but reversible, chemisorption of Cl2 in molecular form. The active species in CH4 and CO chlorination is probably in the radical-like form. Highly strained C-C bonds in the parent carbon materials react irreversibly with Cl2, inhibiting further reaction with CO. In addition, the higher presence of sp3-type defect sites promotes the formation of HCl with deactivation of the reactive C-C sites. The nano-ordering of the hemi-fullerene-type graphene thus reduces the presence of defects and transforms strained C-C bonds, resulting in irreversible chemisorption of Cl2 to catalytic sites able to perform selective chlorination. Tidy up the carbon! CO and CH4 chlorination over hemi-fullerene-type graphene is described. The surface nano-ordering, induced by thermal treatment, transforms strained C-C bond sites resulting in irreversible Cl2 chemisorption to catalytic sites that are able to selectively chlorinate CO and CH4.

Method for synthesizing chloro-2, 2-di (perfluoro substituent)-1, 3-dioxolane compound

-

Paragraph 0049-0050, (2019/07/29)

The invention discloses a method for synthesizing chloro-2, 2-di (perfluoroalkyl)-1, 3-dioxolane. The method comprises the following steps: mixing 2, 2-di (perfluoroalkyl)-1, 3-dioxolane liquid with acatalyst, introducing chlorine gas, heating to the temperature of 100-200 DEG C, and carrying out chlorination reaction to obtain 4, 4, 5, 5-tetrachloro-2, 2-di (perfluoro substituent)-1, 3-dioxolane. The perfluoroalkyl is independently selected from C1-4 perfluoroalkyls or fluorine atoms. According to the method, liquid-phase chlorination reaction is adopted, the reaction temperature is effectively reduced, the activity of the catalyst in the reaction is high, the side reaction is relieved, the requirements on equipment are reduced, the method is safe and simple to operate, the quality stability of the obtained product is high, and the industrial application feasibility is high.
