TL;DR: In this article, a preparation method and application of a bifunctional electrocatalyst of a molybdenum disulfide composite material is described, which belongs to the technical field of electrocatalysts.
Abstract: The invention discloses a preparation method and application of a bifunctional electrocatalyst of a molybdenum disulfide composite material, and belongs to the technical field of electrocatalysts. Thepreparation method comprises the following steps: preparing a precursor ZIF-8@ZIF-67 at first, carrying out carbonization to obtain C-N/Co, then adding C-N/Co, ammonium tetrathiomolybdate and hydrazine hydrate into N,N-dimethylformamide together, preliminarily preparing a molybdenum disulfide composite material through a solvothermal method, and finally, stabilizing molybdenum disulfide compositematerial by heat treatment to obtain a molybdenum disulfide composite material C-N/Co4S3@MoS2. The molybdenum disulfide composite material can be used in hydrogen evolution reactions or oxygen evolution reactions. The molybdenum disulfide composite material has strong conductivity, high atom utilization rate and excellent catalytic performance, and has the advantages of low cost, high efficiency,stability and the like.

TL;DR: In this article, a molybdenum sulfide-ferrite nano-enzyme was used to detect hydrogen peroxide in a high-pressure reaction kettle, and repeatedly cleaned the product; drying the product so as to obtain ferrite magnesium.
Abstract: The invention relates to a molybdenum sulfide-ferrite nano-enzyme as well as a preparation method and an application method thereof. The preparation method comprises the following steps: uniformly mixing ferric chloride hydrate, magnesium chloride hydrate and dodecyl amine with a proper amount of ethylene glycol; enabling the components to react in a high-pressure reaction kettle, and repeatedly cleaning the product; drying the product so as to obtain ferrite magnesium; dissolving ammonium tetrathiomolybdate into dimethyl formamide; slowly adding hydrazine hydrate, and uniformly mixing; putting a proper amount of the ferrite magnesium into the mixed liquid; enabling the components to react in the high-pressure reaction kettle, and repeatedly cleaning the product; drying the product so as to obtain molybdenum sulfide-ferrite magnesium; putting the molybdenum sulfide-ferrite magnesium into a proper amount of TMB (Tetramethylbenzidine) and hydrogen peroxide-sodium acetate buffer solutionsof different concentrations; culturing, and testing the concentration of hydrogen peroxide. Results show that when being adopted to detect hydrogen peroxide, the molybdenum sulfide-ferrite magnesiumnano-enzyme is convenient and rapid to operate, high in sensitivity and wide in detection concentration range.
