A preparation method of ZnO/Ag bilayer negative feedback cathode electrodes was proposed,which can remarkably improve the field emission properties of carbon nanotube(CNT) films.

A new type of single-chamber direct microbial fuel cell was constructed successfully on the basis of studying the cathode electrode containing Fe3+.

In order to improve the stability of low temperature chloride iron plating solution, the effects of five different stabilizers on deposit brightness, cathodic polarization behavior and the stability of the iron plating bath were studied by Hull cell test and cathodic polarization curve measurement.

The nanocrystalline Co-Ni alloys were prepared by jet electrodeposition in the nickel chloride and cobalt sulfate bath containing additive and the cathodic polarization curves of Co-Ni alloys were measured.

In order to study the influence of surfactants on cathodic polarization in the Ni-nanoparticles composite electroplating bath,the curves of cathodic polarization were determined by means of scan potential in the cell of three electrodes.

The cathode polarization curves and cyclic voltammograms during the electroless deposition were tested by LK998Ⅱ model electrochemical analytical system.

Their EIS characteristics under cathodic polarization potential in 0.
