| titleOfInvention | Carbon-spaced barium lanthanum fluoride composite catalyst and preparation method and application thereof |
| abstract | The invention discloses a preparation method of a carbon-spaced barium lanthanum fluoride composite catalyst, which comprises the steps of respectively dissolving barium salt and lanthanum salt in a solvent, mixing and stirring the barium salt and the lanthanum salt, adding a fluorine-containing polymer, drying and roasting the obtained mixed solution to obtain the carbon-spaced barium lanthanum fluoride composite catalyst. The invention also discloses a carbon-spaced barium lanthanum fluoride composite catalyst and application thereof. According to the invention, the fluorination catalyst is directly prepared by using the fluorine-containing polymer as a fluorine source, re-fluorination is not required before reaction, and a carbon layer is formed between barium fluoride and lanthanum fluoride to separate the barium fluoride and the lanthanum fluoride in the roasting process, so that the problem that the barium fluoride and the lanthanum fluoride are easy to form solid solutions at high temperature is solved, and the barium fluoride and the lanthanum fluoride have good catalytic activity in the reaction of synthesizing vinylidene fluoride by co-cracking methane and monochlorodifluoromethane. The method is simple and easy to implement, good in repeatability, high in product selectivity and low in cost. |
