Adsorption Properties

The adsorption properties of two nanomorphologies of trititanate, nanotubes (TiNT) and plates (TiNP), prepared by the hydrothermal reaction of concentrated NaOH with different phases of TiO2, were examined. It was found that the capacity for both morphologies towards methylene blue (MB), an ideal pollutant, was extremely high, with the TiNP having a capacity of 130 mg/g, higher than the TiNT, whose capacity was 120 mg/g at 10 mg/L MB concentration. At capacity, the well-dispersed powders deposit on the floor of the reaction vessel. The two morphologies had very different structural and adsorption properties. TiNT with high surface area and pore volume exhibited exothermic monolayer adsorption of MB. TiNP with low surface area and pore volume yielded a higher adsorption capacity through endothermic multilayer adsorption governed by pore diffusion. TiNP exhibited a higher negative surface charge of −23 mV, compared to −12 mV for TiNT. The adsorption process appears to be an electrostatic interaction, with the cationic dye attracted more strongly to the nanoplates, resulting in a higher adsorption capacity and different adsorption modes. We believe this simple, low cost production of high capacity nanostructured adsorbent material has potential uses in wastewater treatment.

Hierarchical Bi2MoO6 nanosheet arrays (BNAs) growing on three-dimensional (3D) Ni foam are synthesized by one-step template-free route. The obtained BNAs are used as binder-free integrated electrode for Li-ion batteries (LIBs) directly. The electrode exhibits a super high reversible discharge capacity of 2311.7[Formula: see text][Formula: see text]Ah[Formula: see text]cm[Formula: see text] (1741.4[Formula: see text]mAh[Formula: see text]g[Formula: see text]), and an excellent cycle stability. The outstanding electrochemical properties are reasonable from the self-supported integrated electrode in which the electrolyte is easy to infiltrate active materials, electrons and ions are readily transported along the 3D conductive substrate and the stable electrode structure.
