Herein, we present a simple two-step procedure for producing magnetically separable 3-dimensional carbon-coated nickel nanocomposites by calcinating nickel based metal organic framework. According to a room temperature magnetic separable test, the nanocomposites exhibit soft magnetism property, which provides the nanocomposites with a desirable fast magnetic separable property. Maximum adsorption capacity of the nanocomposites for rhodamine B is 84. 5 mg g -1. As a new adsorbent with high efficiency and excellent recyclability, the as-prepared Ni@C nanocomposites can be used in wastewater treatment as a large-scale.
PTFE powders are unzipped to form microsized pores during heat treatment at 600°C. In addition, the PVDF binder has been partially carbonized to produce highly conductive F-doped graphitic carbon. A highly porous platelet SBA-15 template is particularly useful as an SiO 2 active material for large contact areas between SiO 2 and carbonized PVDF. As a result, the more layered SiO 2 /C anode exhibits improved cycle stability and internal resistance than typical SiO 2 electrodes: the unique SiO 2 /C anode's bonded SiO 2 /C anode exhibits greater cycle stability and internal resistance than standard SiO 2 electrodes: the typical SiO 2 /C anode's standard SiO 2 /C anode's simple SiO 2 /C anode exhibits are Li+ dode's.
In which electrodes, flow frames, gaskets, and membranes are continuously stacked in one direction, most of the new redox flow batteries adopt 1-dimensionally stacked cells in which electrodes, flow frames, gaskets, and membranes are repeatedly stacked in one direction. However, these stacked cells suffer from system complexity, high cost, and ineffective cell quality. With this 3-dimensional framework, we were able to demonstrate a zinc bromine battery. Because the porous ceramic structure has multi-functional characteristics as membranes and electrolyte channels as well as cell housing, it does not need expensive membranes or flow frames, thus dramatically lowering the stack manufacturing cost by nearly 60%.
