Problems solved by technology

Nickel ferrite is one of the ferrite metal oxides. It has been widely concerned because of its unique properties. However, nickel ferrite is rarely used in the catalytic degradation of organic matter. In order to expand its performance, the combination with carbon materials is also It has become a research hotspot, but it has not been used for the catalytic degradation of organic pollutants

Abstract

The invention discloses a method for preparing nano carbon composite nickel ferrite. The method comprises the following steps: putting ferric chloride into water, preparing a solution, further addingtetramethyl ammonium bromide and acetone, stirring to obtain an emulsion, further adding sodium hydroxide, stirring acutely, further adding sodium hypochlorite with 10% by mass of available chlorine in the market, continuously and acutely stirring for 2-3 hours, further adding 1-3 g of nickel chloride, continuously stirring for 2-4 hours, performing solid-liquid separation, removing supernate, washing a solid for 3-4 times with distilled water, drying at 105 DEG C, further putting into a muffle furnace, calcining for 4-5 hours at 450-650 DEG C, continuously introducing nitrogen till temperature decreases to the room temperature, thereby obtaining the nano carbon composite nickel ferrite. The method has the advantages that ferrate is generated by using ferric salts, the ferric salts furtherreact with cationic surface active agents and manganese ions, then an organic metal compound is prepared, finally the organic metal compound is carbonized, then the nano carbon composite nickel ferrite is prepared, the production process is simple, and a catalyst effect can be greatly improved.

Description

technical field [0001] The invention relates to the field of new materials for environmental pollution control, in particular to a preparation method of nano-carbon composite nickel ferrite. Background technique [0002] With the development of science and technology, toxic organic pollutants from industrial and agricultural production seriously threaten the environment and human health. It is of great significance to seek a new and efficient environmental governance technology. Photocatalytic technology has become an emerging environmental treatment technology with important application prospects due to its advantages of energy saving, high efficiency, complete pollutant degradation, and no secondary pollution. In recent years, the development of new and efficient visible light photocatalysts has become an important research content in photocatalytic technology. Among them, photocatalytic materials with surface plasmon resonance effect, because of their unique surface physi...
