Manganese dioxide (chemical formula MnO2) nanostructured metal oxide that can form many different crystalline structures, with applications across various engineering fields. One important use of MnO2 is as a catalyst for chemical reactions, and a particular crystalline structure of MnO2, called β-MnO2, is exceptional for the oxidation of 5-hydroxymethylfurfural into 2,5-furandicarboxylic acid (FDCA). Because FDCA can be used to produce environment-friendly bioplastics, finding ways to tune the nanostructure of β-MnO2 to maximize its catalytic performance is crucial.
However, producing β-MnO2 is difficult compared with other MnO2 crystalline structures. Existing methods are complicated and involve the use of template materials onto which β-MnO2 ‘grows’ and ends up with the desired structure after several steps. Now, researchers from Tokyo Institute of Technology led by Prof. Keigo Kamata explore a template-free approach for the synthesis of different types of porous β-MnO2 nanoparticles.
