| 1 | Electrochemical behavior and electrowinning of palladium in nitric acid media显示文摘In this study,the electrochemical behavior of Pd(II)in nitric acid media was investigated using various electrochemical techniques.By analyzing the cyclic voltammogram of Pd(II)recorded at Pt electrode,a series of electrochemical reactions associated with palladium were recognized,indicating that Pd(II)undergoes a single step two-electrons irreversible process.Electroreduction reaction of Pd(II)and auto-catalytic reactions of nitrous acid are supposed to play a leading role in low and high concentrations of nitric acid,respectively.Stirring could facilitate the reduction of Pd(II)in relatively low nitric acid concentration(3 mol/L).The value of charge transfer coefficient was determined to be 0.18 for the measurements at 298 K.The diffusion coefficient of Pd(II)increased from 1.89×10 8cm2/s at 288 K to 4.23×10 8cm2/s at 318 K,and the activation energy was calculated to be 21.5 kJ/mol.In electrowinning experiments,SEM images of palladium obtained by electrolysis reveal the dendrite growth in all cases,which is uniform all over the entire surface of Pt electrode.The recovery ratios of Pd at different nitric acid concentrations are high,and the faradic efficiency of electrolysis decreases with increasing the nitric acid concentration.When stirring was introduced during electrolysis,the electrodeposition rate of Pd increased substantially. | LIU ShengChu WEI YueZhou LIU RuiQin FANG BaiZeng | 2013 | Science China Chemistry2013，56，12： | 3 |

| 4 | Partial discharge characteristics of an air gap defect in the epoxy resin of a saturable reactor under an exponential decay pulse voltage显示文摘Saturable reactor insulation is currently stressed by an exponential decay pulse voltage under normal operating conditions.The partial discharge(PD)characteristics of epoxy resin under an exponential decay pulse voltage were studied here and were compared at 25 and 110℃.In addition,this study compares these PD characteristics with those under a sinusoidal voltage to better measure the insulation design margin of the saturable reactor under an exponential decay pulse voltage.Finally,this study explains the PD mechanism based on the three-capacitor circuit model and space charge accumulation.Compared with the sinusoidal voltage,a higher amplitude,a higher inception voltage and fewer PDs are obtained under the pulse voltage.The reason may be related to the accumulation of space charge.Due to the duality of the space charge effect,the promotion effect of space charge accumulation on the PD under the pulse voltage is dominant,and an increase in temperature will weaken the promotion effect.In contrast,the inhibitory effect of space charge accumulation on the PD under the sinusoidal voltage is dominant.The experimental results can provide a basis for the optimal design of saturable reactor insulation under an exponential decay pulse voltage. | Lu Gui Yan Mi Shengchu Deng Lulu Liu Xin Ge Wenmin Ouyang | 2020 | High Voltage2020，5，4： | 1 |
