Abstract: Carbon nanotubes (CNTs) films electrodes were fabricated by low pressure
and low temperature thermal chemical vapor deposition (CVD) for capacitive
deionization (CDI) application. The CNTs films were mainly composed of
mesopores (2~50 nm) and a small portion of macropores (>50 nm). The pore
size distribution was optimal for CDI application. The CDI capacity was also
dependent on working parameters: Higher ions removal is achieved with
higher applied voltage and an optimal flow rate. The CDI capacity is
dependent on ions properties: monovalent ions with smaller hydrated radii
are preferentially removed from water.
