Hebei Meixi Biotechnology said that basic magnesium carbonate is an important inorganic functional material with a wide range of application prospects. Among them, topography control is one of the important means to achieve its high-performance application. In this paper, the research progress of basic magnesium carbonate morphology control is reviewed, and the preparation methods, performance characteristics and application prospects of basic magnesium carbonate with different morphologies are summarized.
The morphology control of basic magnesium carbonate refers to the control of the shape, size and morphology of basic magnesium carbonate crystals by regulating certain factors in the synthesis process, such as reaction temperature, reaction time, reactant ratio, additives, etc., so as to control their performance and application. At present, common basic magnesium carbonate morphologies include nanoparticles, nanorods, nanowires, nanotubes, and multi-level structures.
Among them, nanoparticles are usually synthesized by rapid reaction such as solvothermal method, hydrothermal method, and microemulsion method. The basic magnesium carbonate has a relatively uniform morphology and particle size distribution, and a large surface area, which can effectively improve its photocatalytic, electrochemical and magnetic properties. For example, it can be used as an electrolyte for dye-sensitized solar cells, gas sensors, biosensors, etc. Nanorods, nanowires and nanotubes are one of the main research directions of topography control. These basic magnesium carbonates are usually synthesized by controlled reaction methods such as hydrothermal, solvothermal, and hydrothermal. Nanorods, nanowires, and nanotubes have high surface area, good conductivity, and shape effects, and can be used in dye-sensitized solar cells, fuel cells, supercapacitors, sensors, and catalysts. At the same time, multi-level structure is another important research direction for the morphology control of basic magnesium carbonate.
The topography of a multi-level structure refers to an architecture that grows from small to large, with an increasingly complex structure. Basic magnesium carbonate with this morphology is usually synthesized by template method, physical magnesium oxide method and other methods. The basic magnesium carbonate with multi-level structure has high specific surface area, good electrochemical performance and biocompatibility. It can be used in biomedicine, catalysts, electronic devices and environmental treatment.
Hebei Meixi Biotechnology said that basic magnesium carbonate morphology control is an effective way to improve its performance and application. Controlling the morphology of basic magnesium carbonate can help improve its photocatalytic, electrochemical, biomedical and environmental management properties, and expand its application prospects. Although some progress has been made in the morphology control of basic magnesium carbonate, there are still many challenges. In the future, it is necessary to further explore the morphology control mechanism and synthesis method of basic magnesium carbonate, and develop it in the direction of higher performance and wider application.
