The present invention provides a method for producing a manganese-doped nickel molybdate electrode material including mixing a nickel salt solution with a manganese salt solution to form a mixture; adding a molybdate solution into the mixture and being subject to a thermal reaction; and obtaining the manganese-doped nickel molybdate electrode material after washing and drying of the reaction product. The nickel salt includes one or more of nickel nitrate, nickel chloride, and nickel acetate; the manganese salt includes one or more of manganese chloride, manganese nitrate, and manganese sulfate; and the molybdate includes one or more of sodium molybdate or ammonium molybdate. The present method utilizes a single reaction to produce a Mn-doped NiMoOelectrode material, which does not require using nickel molybdate as an intermediate product. The method simplifies the preparation process and makes it easy to be adjusted, thereby improving the electrochemical properties of the electrode material.

Provided in the present invention is a preparation method for a nano organometallic carboxylate which effectively solves the problems of a complex washing process, and cumbersome, dangerous and uneconomical preparation of lye in traditional methods for producing organometallic carboxylates. A new method for preparing high-quality organometallic carboxylates by using a carboxylic acid, caustic soda, a metal oxide or a hydroxide as starting materials, and using ball milling to assist reaction thereof. The present invention not only efficiently utilizes lye, it also obtains high-quality organometallic carboxylates, which overcomes the technical prejudice that the prior art uses calcium chloride, sodium chloride and other salts for poor reaction efficiency. The problem in environmental pollution caused by the washing waste liquid in the existing process is fundamentally solved. At the same time, addition of non-ionic surfactants makes ball milling more efficient and significantly reduces the particle size of the product.

A method for preparing a color masterbatch with a natural dye is disclosed. The new method uses a phase change material tetradecane as one of the solvents to extract the natural dye, the extracted natural dye as a core material, and polybutylene succinate as a wall material to microencapsulate the natural dye containing the phase change material by a solvent evaporation method to prepare natural dye microcapsules, then melt-blends with a carrier resin, extrudes and granulates to obtain the color masterbatch with the natural dye. The microencapsulation improves the thermal stability of natural dye and compatibility with carrier resin The obtained color masterbatch with natural dye has excellent heat resistance, and the fabric obtained after spinning with it has good color fastness to hot pressing.
