A new method for Nitrate-N removal in water has been presented in this paper, and related experiments have been carried out to study its technical characteristics. Results showed that in designed electrolysis system, Fe modified Ti substrate cathode can catalytic reduce NO3--N to NH4+-N under suitable conditions. Furthermore NH4+-N can be oxidized to N2-N in same system by supporting of Cl-. Under...
This study analyzed the composition of residual gases inside a vacuum-sealed panel, which was composed of a CNT emitter cathode plate, a phosphor anode, and glass spacers, all kept in vacuum, revealing that CO, CO2, N2, CH4, H2, C2H6, and Ar existed inside the panel. The CNT emitter cathode was prepared in a diode structure by using the CNT paste, producing an array of dots with a diameter of 10 mum...
Summary form only given. We study the work functions of cathode surfaces with adsorbed atoms by using ab initio calculations. We used the standard slab geometry to model the surface systems. The tungsten (W) substrates are modeled by 5-layer slabs for the W (001) orientations. This provides one surface as well as bulk regions in all of the slab, which approximate the atomic structure encountered in...
