摘要：
One-dimensional (1D) alpha-MnO2 nanowires (NWs) and beta-MnO2 nanorods (NRs) were synthesized by hydrothermal method. The effects of reactant concentration on the phase and morphology of the products have been investigated. The structural and optical properties were investigated by XRD, SEM, EDS and UV-vis, FTIR spectroscopy. The absorption spectra of alpha-MnO2 NWs and beta-MnO2 NRs exhibit a band gap of 5.49 and 5.37 eV, which are blue shifted from bulk. Fourier transform infrared (FTIR) spectroscopy confirmed the Mn-O bond.
