The XRD results reveal that MnO2 is the form of beta-MnO2. The TEM and SEM results show that MnO2/CNTs nanocornposites are composed of MnO2 nanorods with the diameters 60-80 nm and CNTs with the diameters 40-50 nm twisted structure. As cathode materials for lithium ion batteries (LIBs),...
Highly dispersed beta-MnO2 nanorods are prepared by a simple one-step hydrothermal synthesis method. The structure and morphology of the beta-MnO2 nanorods are investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The supercapacitive...
SEM images showed nanorod shape of all specimens, while microstructure characterization done by XRD measurements revealed that crystallites have an elongated rod-like shape and, hence, it confirmed the anisotropic morphology. Magnetic ordering of beta-MnO2 is antiferromagnetic below 93 K, while both ...
Magnetic photocatalyst beta-Bi2O3/beta-MnO2/MnxZn1-xFe2O4 (BM/MZF) was successfully synthesised using dip-calcination method. The structure and properties of as-prepared samples were characterised by XRD, SEM, FT-IR, UV-DRS and VSM. The peaks of beta-Bi2O3 and beta-MnO2 without an ...
