摘要:The present invention provides a method for the continuous synthesis of a substituted benzoic-acid organic substance. The continuous synthesis method comprises: in the presence of catalyst and organic solvent, the organic matter represented by formula (I) and oxygen are continuously inputted to a continuous reaction apparatus for continuous oxidation reaction to obtain a substituted benzoic-acid organic substance, which is discharged continuously, the substituted benzoic-acid organic substance having the structure represented by formula (II). Oxygen is a green reagent and is inexpensive and readily available; a large amount of wastewater, waste gas, and solid waste is not generated after the reaction, and the system is easy to handle. The use of a continuous reaction operation can reduce the risk of flash distillation and explosion of solvent due to a high concentration of oxygen in a batch reaction. Under the same oxidation conditions, the continuous preparation process can reduce the escape of oxygen, greatly increasing the oxygen utilization rate and also simplifying the operation, improving the safety of the reaction and the yield of the substituted benzoic-acid organic substance.

摘要:The disclosure herein discloses a general method for the synthesis of FeCoNiCu-based high-entropy alloy and their application for electrocatalytic water splitting, belonging to the technical field of preparation of composite materials. The catalytic material for electrolysis of water includes a reaction active material and a support. The reaction active material is FeCoNiCu-based high-entropy alloy nanoparticles such as FeCoNiCuSn, FeCoNiCuMn, FeCoNiCuV or the like. The support is a carbon nanofiber material prepared by electrospinning. The catalytic material for electrolysis of water prepared in the disclosure herein has a high specific surface area, which facilitates diffusion of the electrolyte and desorption of gas. By using the catalytic material for electrolysis of water, hydrogen and oxygen can be produced under alkaline conditions, and the hydrogen production rate under high voltage is much higher than that of a 20% Pt/C electrode. Meanwhile, the carbon nanofibers can effectively protect the high-entropy alloy nanoparticles from erosion of the electrolyte, and endow the catalytic material with good stability.
