Abstract:

Biochar, a by-product of biomass pyrolysis, was investigated as a carbon-based electrode material for a water treatment method based on electrostatic adsorption/desorption of ions in electric double layers (EDLs) formed on the charged electrodes (capacitive deionization, CDI). Surface area, porous structure, and functional groups of biochar were developed, and corresponding effects on EDL capacitive performance were studied. A novel method was explored to tailor the micro- and meso-porous structures of activated biochar by exploiting the interaction between pre-carbonization drying conditions

In addition, the resolution of PZT based transducers is low due to the limitation in hand-fabrication methods of the piezoelectric ceramics. Capacitive Micromachined Ultrasonic Tr

Abstract:

The effects of system pressure on the performance stability of flow-through capacitive deionization (CDI) cells was investigated. Initial data showed that the highly porous carbon electrodes possessed air/oxygen in the micropores, and the increased system pressure boosts the gases solubility in saline solution and carries them out of the cell in the effluent. Upon applying a potential difference to the electrodes, capacitive-based ion adsorption occurs in competition with faradaic reactions that consume oxygen. Through the addition of backpressure, the rate of degradation decreases, allowing t

A more energy efficient and sustainable method of desalinating water is needed due to increasing water shortages and contamination of current freshwater sources.

CDI uses less applied energy than more commonly used methods of desalination like reverse osmosis and multi-flash distillation and has the added advantage of energy recovery.

Carbon Aerogel were prepared using resorcinol and formaldehyde catalyzed by KOH in a sol–gel process followed by carbonization, during which the KOH serves as an activating agent and increase specific surface area, and it was modified by adding mesopore titania to carbon precursor for increase mesopore volum. The electrode was fabricated by polymer binder and conductive filler, which to probe into the

碩士<br>國立臺灣大學<br>環境工程學研究所<br>106<br>Membrane capacitive deionization (MCDI) is a promising desalination technology with low energy input and high water recovery. Electrode materials play an important role for determination of the desalination performance. Generally, there are two fundamental mechanisms: (1) capacitive electrosorption using highly porous carbons, and (2) pseudocapacitive ion storage using redox materials (i.e., MnO2). Most recently, to achieve high salt adsorption capacity (SAC) of electrode materials, many efforts have been made on the development of pseudocapacitive materials,

碩士<br>國立中央大學<br>環境工程研究所<br>107<br>Capacitive deionization (CDI) is a rising technology for water desalination. CDI is based on the electrosorption of ions onto the electrical double layer (EDL) of electrode surface which formed by applying low voltage, and the desorption is processed easily by removing voltage. There has been a dearth of research about the CDI performance when there is organic compounds in wastewater for reuse. The biologically treated still contains dissolved organic matter (DOM) which cannot be treated completely by the secondary process, and it will block the pores of carbo

Based on the principle of capacitive deionization (CDI), the ions are removed by applying electric field and ions, which stored in the surface of porous carbon electrodes from aqueous solution. During the process of electrosorption, the IEM plays an important role to exclude the co-ion effect due to the characteristic of permselective.

碩士<br>國立交通大學<br>環境工程系所<br>105<br>Capacitive deionization (CDI) technology is the use of an external voltage for generation of electrode capacitance, thereby removing ions from the aqueous solution. Carbon material applied in the CDI technology include activated carbon, mesoporous carbon material and carbon nanotubes, which store charge with the mechanism of electrical double layer capacitance. Activated carbon processes a very high specific surface area, however, due to poor conductivity of activated carbon, carbon black can be then incorporated therein to improve the overall specific capacit
