Synthesis And Properties Of Dimethylglyoxime Nickel-Based Composite Materials

Metal organic framework materials are widely used in storage,separation,catalysis and other fields due to their unique structural characteristics.The nickel-based MOFs have also attracted widespread attention due to its abundant reserves and low prices.There have been reports in the literature that nickel-based MOFs have certain applications in gas adsorption,capacitance,etc,but their research on photocatalysis and wettability is less.Therefore,in this paper,[Ni?DMG?₂]and its composites were prepared by different methods and a thin film of the product was prepared by the screen printing process to investigate the photocatalytic performance and wetting performance.This article is mainly about the following four aspects:?1?[Ni?DMG?₂]was prepared by using two simple water bath method and reflux method,using NiO as the nickel source,and the crystal form and morphology of the product were investigated by XRD,SEM and other characterization methods.The product was prepared into a film based on filter paper and filter cloth through a screen printing process,and the photocatalytic properties of the product film and the wettability of the film were investigated.At the same time,the effects on the morphology and properties of the products were investigated by adding different surfactants.?2?CdS/[Ni?DMG?₂]composites with different mass ratios were prepared using the water bath method with NiCl₂·6H₂O as the nickel source,and glass-film-based films were prepared by screen printing process.Quinoline blue?QB?and Rhodamine B?Rh B?are the target dyes to investigate the photocatalytic performance of thin films.Similarly,a film based on filter paper and cloth was prepared by a screen printing process to investigate its wettability.In addition,a series of CdS/[Ni?DMG?₂]composites were prepared by changing the reaction temperature,reaction time,p H and other factors to further explore the effect on the photocatalytic performance of the thin film.?3?CeO₂/[Ni?DMG?₂]composites with different molar ratios were prepared by using hydrothermal method with Ni?NO₃?₂·6H₂O as the nickel source.Films based on filter paper were prepared by screen printing to investigate the chemical stability of the films and oil-water separation performance.At the same time,a series of CeO₂/[Ni?DMG?₂]composite films were prepared by changing the hydrothermal time and adding different surfactants and further explored the effect on the film wettability.?4?A series of nickel[Ni?DMG?₂]nickel foam were prepared by using mild in-situ growth method,using nickel foam as the nickel source,and changing the soaking time and nitric acid concentration.After modification with fluorosilane,a superhydrophobic[Ni?DMG?₂]nickel foam was obtained.The chemical stability of the film was investigated by immersing it in a strong acid and alkali solution and a salt solution.In addition,the mechanical durability of the film was explored through friction experiments and ultrasonic experiments;the oil-water separation performance of the films and the cycle practicality were explored through the separation of various oils.
