Abstract

The invention relates to a nickel-based magnetic compound material as well as a synthesis method and application thereof. The synthesis method comprises the following steps: adding deionized water into NiCl2.6H2O, N,N'-bis(4-methylene pyridine)benzene-1,4-dicarbonamide and trimesic acid, carrying out hydrothermal reaction in a high pressure reactor, and generating an organic ligand Ni complex [Ni3(4-bmbpd)3(BTC)2(H2O)4].4H2O; and grinding and smashing the Ni complex by adopting an agate mortar, dispersing into ethyl alcohol, grinding by adopting a ball grinding mill, carrying out centrifugal separation to obtain a microcrystalline Ni complex material, placing into a tubular furnace under the protection of nitrogen, and calcining, so that the nickel-based magnetic compound material is obtained. The nickel-based magnetic compound material is applied to photocatalytic degradation of an organic dye pollutant material. The nickel-based magnetic compound material provided by the invention has the advantages that catalysis speed is high, efficiency is high, recycling and reusing can be facilitated, photocatalytic degradation rate on a methylene blue organic pollutant can reach 96% and thenickel-based magnetic compound material can be taken as a methylene blue organic pollutant photocatalytic degradation material.

Description

technical field [0001] The invention belongs to the field of synthesis of catalytic materials, in particular to the synthesis and application of a nickel-based magnetic N-C composite material. Background technique [0002] Printing and dyeing wastewater is the production wastewater discharged from printing and dyeing factories that mainly process cotton, hemp, chemical fibers and their blended products. Printing and dyeing wastewater has a large amount of water, 100-200 tons of water is consumed per ton of textile printing and dyeing, and 80-90% of it becomes wastewater. Dye lost in wastewater accounts for 15% of dye production, causing enormous environmental pressure. Among various dyes, methylene blue can be used in the dyeing of hemp, silk fabrics, paper, bamboo and wood; it can also be used in the manufacture of inks and lakes, and the dyeing of biological and bacterial tissues. Because the dye has good water solubility, it has a high loss rate during production and us...
