电解法制备次氯酸钠用电极材料的研究进展
Research progress on electrode materials for the preparation of sodium hypochlorite by electrolysis
摘要
Abstract
Sodium hypochlorite(NaClO)is widely used as an efficient and inexpensive disinfectant.Electrolysis is a convenient and effective way to produce NaClO with electrodes being the core component of a NaClO generator.These electrodes determine the device's chlorine evolution efficiency,energy consumption and service life.Currently,titanium electrodes coated with mixed metal oxides(Ti/MMO)have become a research focus due to their excellent electrocatalytic activity,long service life and low energy consumption.However,the production cost remains high due to the use of precious metal materials.This paper summarized various electrode materials used for the electrolytic production of NaClO,their composition,performance and development trends.It analyzed the reasons for the passivation of early dimensionally stable anodes(DSA)and focused on three approaches for optimizing electrode preparation processes.Considering current research challenges,the paper anticipated the future development directions of electrode materials,highlighting the rational selection and diversification of metal elements in coatings,the introduction of titanium dioxide nanotube arrays(TNT)intermediate layers via in-situ anodic oxidation,and the combination of hydrothermal synthesis method for electrode preparation as key aspects of process optimization.关键词
