Hierarchically assembled carbon nanosheets with a high surface area and an ultra large pore volume were derived by the direct carbonization of an adipic acid and zinc powder mixture. This structure enables fast ion and electron kinetics, resulting in an enhanced electrochemical performance of lithium–sulfur batteries.

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.

And Storage

Mesoporous carbons (with up to 95% of pore volume from mesopores) with surface area and pore volume of ∼4000 m2 g−1 and ∼3.6 cm3 g−1, respectively, are excellent CO2 absorbers under pre combustion conditions and can store 55 mmol g−1 (i.e., 2.42 g g−1) or 930 g l−1 at 25 °C and 50 bar.
