anodic metal
1.MODEL OF ANODIC DISSOLUTION OF METAL WITH MOH AND MO FILMS AND ITS CHAOTIC DYNAMICS
2.The nano-material precursors of metal alkoxides and theirs complexes are prepared by anodic dissolution of metal in non-aqueous media with a small quantity of ion-conductive additive and acetylacetonate under 3 0-40 .In the second part preparation and characterization of nano-sized NiO and ZnO are studied.
3.The potentiostatic electrosynthesis of Ti(EtO) 4 was studied by anodic dissolution of metal titanium(TA1) in solution of 0.005 mol·L -1 (EtO) 4NBr in the ethanol (AR) in the presence negligible CH 3COCH 2COCH 3.The Ti_based nanocrystalline TiO 2 Film electrode (Ti/nano_TiO 2) was prepared by sol_gel method.
4.Large area, well-aligned and uniform titania nanotube arrays were fabricated by anodic oxidation of titanium metal in HF aqueous solution at room temperature. SEM photographs show that nanotube arrays have an average diameter of ～100 nm with a thickness of ～200 nm when anodizing titanium foils at 20 V in 1% HF solution for 15 min.
6.The experimental results showed that the samples have high purity,and their structure of the samples was as same as the bulk material,that was, bcc structure with an average size of 43 nm ranging from 20 nm to 70 nm distributed uniformly in spherical chain shapes. The specific surface area is 17.54 m~2/g. The method of anodic arc discharging plasma has potential application for producing nano-metal materials.
7.(2) The anodic Pb(Ⅱ) oxides film is reduced via a dissolution-precipitation mechanism during the negative LSV. At first, the surface layer of the PbO particles is reduced to the metal Pb, and then the PbO and PbO·PbSO 4 particles are reduced together, when the metal Pb in the surface layer of the PbO particles meets the PbO·PbSO 4 particles, and the reduction of PbO·PbSO 4 particles is slightly faster than that of the PbO particles.
