简介:Carbon nanotubes (CNTs) were hot-pressed as the electrodes of flow-through capacitor (FTC), which were used to remove NaCl from
saltwater solution. The electrodes, obtained by hot-pressing CNTs with at least 20% phenoli简介:Carbon nanotubes (CNTs) were hot-pressed as the electrodes of flow-through capacitor (FTC), which were used to remove NaCl from
saltwater solution. The electrodes, obtained by hot-pressing CNTs with at least 20% phenolic resin (PR) binders, were investigated with
battery-testing, nitrogen adsorption, scanning electron microscopy (SEM), atomic force microscope (AFM) and water contact angle. The
results showed that the binders deteriorated the performance of the electrodes, and carbonization improved removal of NaCl from saltwater
solution, with the efficiency up to 90%. After the electrodes being carbonized, many new pores were created on the surface; the specific surface area highly increased; the equivalent resistance greatly decreased; the hydrophilicity highly increased; the specific capacitance tremendously increased; thus, removal efficiency highly increased.详细>
