How to do the best volume impregnation to prepare a supported catalyst?

How to do the best volume impregnation to prepare a supported catalyst?

Answer:

Take a certain amount of material measured its saturated adsorption volume, then this part is in the back of the impregnation of the precursor solution, it can not be used to be lost? The amount of catalyst used to do not measure the saturation adsorption volume with water immersion carrier , After the completion of the carrier can also be used. Drying (station contact TA) You may have a problem with this system, CeO2 part of the water, PtCl2 aqueous solution is strong acid, the carrier will dissolve!
A certain amount of material by adding excess water, immersed for a period of time after the filter, calculated by the amount of material to be adsorbed by the amount of water, so as to get the saturated adsorption capacity of the material bolted (station contact TA) recommended the use of insects have resources bingyu0729 ( Station contact TA) take a certain amount of material to measure its saturated adsorption volume, then this part is in the back of the impregnation of the precursor solution, it can not be used to be lost? The amount of catalyst to do is not much zhangwengui330 (station contact TA) and other volume impregnation is not the most homogeneous preparation method, in order to achieve uniform control, often take the method of adding additives such as microemulsion
