不锈钢基/β-PbO2-TiO2-CO3O4复合镀层制备及其性能表征
Preparation and Characterization of β-PbO2-TiO2-Co3O4 Composite Coating on StainlessSteel
摘要
Abstract
β-PbO2, TiO2 -doped β-PbO2, Co3O4-doped β-PbO2 and TiO2/Co3O4-doped β-PbO2 composite electrodes were prepared on stainless steel by current electrodeposition. The morphology, elemental composition, structure and catalytic activity of the composite electrodes were characterized by SEM, EDS, XRD and electrodeposition. The results show that the doping of TiO2 refines crystal grains and increases surface area, and the doping of Co3O4 improves the catalytic activity of the oxygen evolution. Compared with Pb-Ag electrode, the β-PbO2-TiO2-Co3O4 composite anode has longer life, and the bath voltage was decreased to 2. 97 V, and the current efficiency was increased to 91. 2% in zinc eleclrowinng.关键词
