Preparation method of manganese-based catalyst, prepared catalyst and application

The invention relates to the technical field of catalyst preparation, and discloses a preparation method of a manganese-based catalyst, the prepared catalyst and application, the method comprises the following steps: (1) mixing a mixed solution containing MnO2 and a noble metal precursor hydrolysis auxiliary agent with a noble metal precursor, and separating to obtain a solid product; and (2) washing and calcining the solid product in the step (1) to obtain the manganese-based catalyst, in the step (1), the mass ratio of the noble metal precursor to MnO2 (metered by metal elements) is (0.0005-0.03): 1. According to the method, monatomic dispersion of noble metal is realized on the surface of a MnO2 carrier by regulating and controlling the hydrolysis process of a noble metal precursor, the manganese-based catalyst is obtained through calcination treatment, and the prepared catalyst effectively reduces the CO catalytic oxidation reaction temperature.

Carbon nanomaterial-loaded fiber and method for preparing the same

ActiveCN119265925BFibre types
The application provides a carbon nanomaterial loaded fiber and a preparation method thereof. The preparation method comprises the following steps: mixing carbon nanomaterial, a dispersing agent and a solvent to perform dispersion, to obtain a carbon nanometer dispersion liquid; loading the carbon nanometer dispersion liquid on the surface of a fiber to obtain a carbon nanometer dispersion liquid loaded fiber; and performing coagulation bath treatment on the carbon nanometer dispersion liquid loaded fiber, and drying, to obtain the carbon nanomaterial loaded fiber. The loading method of the carbon nanomaterial is simple, efficient and low in cost, and a complex dispersion liquid formula is not required. The carbon nanomaterial loaded fiber has high purity, does not contain other auxiliary additives except the carbon nanomaterial and the fiber, and has strong coating force and good stability.
