摘要

以高锰酸钾和抗坏血酸为原料，摩尔比为1∶(1 - 1.5)，在空气中退火，采用微波辅助水热法合成立方α-Mn2O3。提出了氧化锰（III）形成的可能机理。采用粉末x射线衍射、扫描电镜和低温氮气吸附等方法对合成的α-Mn2O3进行了主要理化性质的测定。研究发现，通过改变反应混合物组分的摩尔比和前驱体的退火条件，可以得到β-MnO2、Mn3O4、MnO/C和Mn3O4/C复合材料。

Microwave-Assisted Hydrothermal Synthesis of α-Mn2O3

Cubic α-Mn₂O₃ was synthesized by microwave-assisted hydrothermal treatment of a reaction mixture containing potassium permanganate and ascorbic acid taken in a molar ratio of 1: (1–1.5) followed by annealing in air. A possible mechanism for the formation of manganese(III) oxide was proposed. The main physicochemical characteristics of the synthesized α-Mn₂O₃ were determined using powder X-ray diffraction, scanning electron microscopy, and low-temperature nitrogen adsorption. It was found that β-MnO₂, Mn₃O₄, and MnO/C and Mn₃O₄/C composites can be additionally obtained by varying the molar ratio of the components of the reaction mixture and the conditions of annealing of the precursors.
