氧化电解水作为一种新型、高效、环保的杀菌剂,具有广阔的应用前景。但目前在氧化电解水制备过程中,其阳极电催化材料存在效率低和使用寿命短等问题。采用亚当斯融合法制备了Ir_(0.5)Pt_(0.5)O_2复合氧化物电极。通过XRD表征,其晶型为典型的金红石型结构。SEM结果表明虽然颗粒之间存在团聚现象,但是可以明显观察到大量蜂窝状结构存在,提高了催化剂的比表面积和电化学面积。进一步的CV表征证明了这一点,同时在CV图中表现出明显的铂铱复合氧化物结构的特征。利用LSV技术分别考察了Ir_(0.5)Pt_(0.5)O_2的析氯和析氧极化曲线,发现其单位表观面积上析氯活性明显提高,而析氧活性明显降低。计算表明Ir_...

Electrolyzed oxidizing water (EOW), as an innovative disinfectant characterized by its high efficiency, broad antimicrobial spectrum, and non-toxic residues, has been broadly used in health care industry, medicines, agriculture, and food processing. EOW is usually generated by electrolysis of a dilute NaCl solution in a chamber with two cells separated by membrane, and is obtained from the anode side. But low current efficiency and short service life of the anode in EOW generators restrict the application of EOW. Ir0.5Pt0. 5O2 anode was prepared by the improved Adams fusion method. The propert...
