In this paper, we present a fast and green method to prepare Li0.44MnO2 nanorods by Li/Na ion exchange of Na0.44MnO2 templates. XRD and SEM confirm that the products still maintain the crystal and geometric structure of Na0.44MnO2 temples. Electrochemical tests show the capacity of Li0.44MnO2 nanorods is up to 218 mAh · g-1 at the current density of 0.1 A · g-1. Especially, the capacity of electrode is still located at 90 mAh · g-1 at the current density of 5.0 A· g-1 after cycling for 100 times. So Li0.44MnO2 nanorods have a potential application in the next generation of advanced batteries.

In this work, the potential application of TiO2-Fe-HNT photocatalyst-adsorbent composite in water treatment technologies was confirmed. The photocatalyst-adsorbent composite (TiO2-Fe-HNTs) was synthesized by the hydrothermal method and characterized by X-ray diffraction, thermogravimetric analysis, Fourier-transform infrared spectroscopy, scanning electron microscopy-energy dispersive X-ray spectroscopy, and diffuse reflectance spectroscopy. The adsorption and photocatalysis mechanism by the TiO2-Fe-HNT composite were examined on methylene blue dye, rhodamine blue dye, naproxen sodium (pharmaceutical drug waste), and imidacloprid (pesticide). The TiO2-Fe-HNT composite was active in UV and visible regions of the electromagnetic spectrum. The adsorption and photocatalytic efficiency increased with increasing amount of HNTs. The photocatalyst-adsorbent composite exhibited excellent removal efficiency for pharmaceutical waste (naproxen sodium) and pesticides (imidacloprid). An adsorption equilibrium data fitted well with the pseudo-second-order kinetics for both methylene blue and rhodamine blue dyes with the intraparticle model describing its rate-controlling steps. The Langmuir and Freundlich isotherm models further described the adsorption of methylene blue and rhodamine blue molecules, respectively.
