The preparation of alpha-MnO2 nanotubes (M-NT) decorated with platinum nanoparticles (Pt/M-NT) by a simple reduction and mechanical stirring method is presented in this work, which aims to design a highly active catalyst for the Li-O-2 battery. The obtained samples were characterized by XRD...
Single-crystal alpha-MnO2 nanorods were grown on multi-walled carbon nanotubes (MWNTs) in H2SO4 aqueous solution. The morphology and microstructure of the composites were examined by transmission electron microscopy, high-resolution transmission electron microscopy (HRTEM), X-ray diffractometry and energ...

Therein, MnO2 provides an advantage owing to its selective catalytic effect, simple fabrication methods, good adsorption capacity, and relatively low cost [23], which makes it as an ideal functionalized material for catalytic decomposition of H2O2 [24]. Therefore, it could replace some biocatalysts ...
