Abstract

The invention relates to a preparation method of nano-scale manganese ferrite catalyst with high specific surface area. The method comprises the following steps: (1)dissolving ferric salt and manganese slat in deionized water according to the proportion that the mole ratio of the Fe element to the Mn element is (1.8-2.2):1, and preparing a solution A; (2) adding an organic fuel in the solution A prepared in the step (1), then adding inert salt NaCl, dissolving and regulating pH to prepare a raw material solution; (3) burning the raw material solution prepared in the step (2), cleaning and drying to prepare the nano-scale manganese ferrite catalyst with high specific surface area. The method disclosed by the invention is relatively low in ignition temperature, less in preparation energy consumption, short in reaction time and high in speed.

Description

technical field [0001] The invention relates to a preparation method of a nano-scale manganese ferrite catalyst with a high specific surface area, belonging to the technical field of nanocomposite materials. Background technique [0002] Spinel-type oxides are usually composed of one or two transition metal oxides. Because of their unique physical properties, they are widely used in electrode materials, catalytic materials, luminescent materials, sensing materials, and conductive materials. Manganese ferrite (chemical formula MnFe 2 o 4 ) is a kind of spinel-type ferrite, and its crystal structure is similar to the natural mineral spinel MgAl 2 o 4 Similarly, it belongs to the miscible spinel configuration, and its preparation process requires high requirements. [0003] At present, the preparation methods of nano-manganese ferrite mainly include solid-phase sintering method, chemical co-precipitation method, hydrothermal (solvent) method, sol-gel method, microemulsion m...
