Abstract

The invention discloses a device for quickly detecting the impregnation amount in real time and a using method thereof and relates to a detection device and a using method thereof. The device for quickly detecting the impregnation amount in real time and the using method of the device mainly solve the technical problem that the existing method for detecting the impregnation amount wastes time and labor and can not perform real-time detection, so that the concentration of impregnation solution cannot be reflected timely, and deviation exists between the impregnation result and the theory. The device for quickly detecting the impregnation amount in real time comprises a detection system, an impregnation solution guide pipe, an impregnation test sample, an impregnation tank, an impregnation solution circulation pump and a stirring device. The using method of the device comprises the steps of 1, establishing a relational data base of molar concentration of solute of the impregnation solution and transmissivity through the device for quickly detecting the impregnation amount in real time; 2, detecting the impregnation solution of a real-time sample during impregnation; and 3, performing calculation to obtain the impregnation amount of the sample. The device for quickly detecting the impregnation amount in real time and the using method of the device can be applied to the fields of material modification, material surface modification and batteries.

Description

technical field [0001] The present invention relates to detection devices and methods of use thereof. Background technique [0002] The impregnation method is a common method for the preparation of supported catalysts, material modification and surface modification, which has the advantages of simple operation, low input cost and wide application range. At present, it is also widely used in the field of preparation of fuel cell electrodes, such as the preparation of Pt electrodes in proton exchange membrane fuel cells and the preparation of Cu-based and Ni-based anodes in solid oxide fuel cells. The supported catalyst prepared by the impregnation method can also reduce the usage of active components of the catalyst and reduce the cost to a great extent, so it is of great significance to promote it in practical applications. [0003] The impregnation amount of catalyst active components affects the physical and chemical properties of materials to a great extent. The impregn...
