Abstract

The invention discloses a Prussian blue analogue nano framework material as well as a preparation method and application thereof, and belongs to the technical field of materials. Ferric sulfate, manganese sulfate monohydrate and potassium ferricyanide are used for synthesizing a ferromanganese Prussian blue precursor, the precursor is dispersed with water, a cobalt chloride hexahydrate solution is added, ion exchange, centrifugation, washing and freeze drying are carried out, then the ferrocobalt Prussian blue nano frame material is obtained, and under the mild condition, high-activity photocatalytic reduction of carbon dioxide into carbon monoxide can be achieved. The ferrocobalt Prussian blue nano frame material is prepared by a redissolution-recrystallization method, and can be popularized to salts of nickel, copper and the like. The method has the characteristics of simplicity in operation, short preparation period, high economic benefit, strong universality and applicability, suitability for large-scale production and the like, has remarkable economic benefit and environmental benefit, and is beneficial to popularization and application.

Description

technical field

[0001] The invention belongs to the technical field of materials, and in particular relates to a highly active reducing CO 2 Preparation method and application of Prussian blue analogue nanoframe material. Background technique

[0002] In recent years, metal-organic frameworks (MOFs) have been widely studied due to their advantages of various types, many pores, good catalytic performance and adjustable structure. In addition, due to its open three-dimensional structure, it has great application potential in photocatalytic systems. The method based on redissolution-recrystallization has opened up new methods and ideas for the preparation of new functionalized metal-organic frameworks (MOFs).

[0003] In the past, few studies have focused on using MOFs to construct nanoframes. The main reason is that it is difficult to find suitable MOFs templates to selectively remove the sides of MOFs. When Prussian blue is used as a template, new functional nanomaterials ...
