RuO_2和IrO_2都是用于析氧、析氯的氧化物阳极的活性组分,作为阳极材料用于氯碱、氯酸盐制备、电解水、电冶金以及废水处理等领域具有很大的潜力.RuO_2和IrO_2能形成固溶体.IrO_2。的加入,提高了电极的稳定性,降低了电极的析氧催化活性.这种混合氧化物Ir_aRu_(1-a)O2阳极已用于酸性介质中电解水.对于Ru-Ir合金电极和混合氧化物电极已进行了大量的电化学和表面性质的研究.但关于热分解制备的RuO_2-IrO_2电极的研究报道尚少,面对表面性质的研究更少.本文应用XPS和电化学技术研究热分解制备RuO_2-IrO_2电极的电化学性能和表面性质的关系,以探讨制备寿命长、价格低的阳极的可能途径.
Both RuO_2 and IrO_2 are active components of oxide anodes for oxygen evolution and chlorine evolution and have great potential as anodic materials in the fields of chlor-alkali, chlorate preparation, electrolyzed water, electro-metallurgy and wastewater treatment.RuO_2 And IrO_2 can form solid solution .IrO_2. Of the mixed oxide Ir_aRu_ (1-a) O2 anode has been used for electrolysis of water in an acidic medium for the Ru-Ir alloy electrode and mixed oxidation However, there are few reports about the RuO 2 -IrO 2 electrode prepared by thermal decomposition and few studies on its surface properties.In this paper, X-ray diffraction (XPS) and electrochemical techniques are used to study the thermal decomposition Preparation of RuO_2-IrO_2 electrode electrochemical properties and surface properties of the relationship to explore the preparation of long life, low-cost anode possible way.
