The catalyst inks were prepared by dispersing the catalyst nanoparticles into an appropriate amoimt of Millipore water and 5wt% Nafion solution. Then, both the anode and cathode catalyst inks were directly painted using a direct painting technique onto either side of a Nafion 117 membrane. A carbon cloth diffusion layer was placed on to top of both the anode and cathode catalyst layers [3-5]. The active cell area was 2.25cm. ... 

In recent years, many types of double-layer capacitors have been built with porous or extremely rough carbon electrodes. Activated carbon or materials produced by carbonization and partial activation of textile cloth can be used for these purposes. At carbon materials, the specific capacity is on the order of 10 J,F/cm of trae surface area in the region of ideal polarizability. Activated carbons have specific surface areas attaining thousands of mVg. The double-layer capacity can thus attain several tens of farads per gram of electrode material at the surfaces of such carbons. 

Be careful to keep track of which side is the active side of the catalyst impregnated carbon cloth. The active side has more of the carbon-platinum binder powder and is smoother. 

Carbon Industries, a subsidiary of Messier-Bugatti Co., is acknowledged for the supply of activated carbon cloths. 

Activated carbon cloth of 1-1.1 mm thickness was used as the initial material for most of experiments. Ribbon, made of carbon cloth, was soaked in the solution with 40wt% KOH and 10 g-1-1 LiOH for 72 hours, and afterwards, was cut into electrodes of the appropriate dimensions. Electrolyte surplus was removed by pressing. 

Removal of Catechol and Resorcinol from Aqueous Solution by Adsorption onto High Area Activated Carbon Cloth... 

Abstract Removal of catechol and resorcinol from aqueous solutions by adsorption onto high area activated carbon cloth (ACC) was investigated. Kinetics of adsorption was followed by in-situ uv-spectroscopy and the data were treated according to pseudo-first-order, pseudo-second-order and intraparticle drfiusion models. It was fotmd that the adsorption process of these compotmds onto ACC follows pseudo-second-order model. Furthermore, intraparticle drfiusion is efiective in rate of adsorption processes of these compoimds. Adsorption isotherms were derived at 25°C on the basis of batch analysis. Isotherm data were treated according to Langmuir and Freundhch models. The fits of experimental data to these equations were examined.

Activated carbon cloth ACC used in the present work was provided by Spectra Corp. (MA, USA) coded as Spectracarb 2225. The pesticide metobromuron was obtained from Riedel de Haen. The chemical stmcture of that pesticide is given in Fig. 22.1. Deionized water was used in adsorption experiments.
