Preparation Process of Coating Ti Anode for Generating Electrolyzed Oxidizing Water and Its Effects

Abstract:

To reduce the preparation costs of coating Ti anode for generating electrolyzed oxidizing water (EOW),and improve its electrolysis efficiency and service life,RuO2SnO2TiO2 were used as metal oxide coating to analyze the effect of Ru on the performance of coating Ti anode.The effects of sintering temperature,heat treatment time on the properties of coating Ti anode were investigated.Results indicate that Ru processes electrocatalytic activity,and plays a vital part in the geometrical coating configuration,reinforcement of catalytic activity in chlorine dissociation reaction and the anode longevity.When Ru scales below 30%,there is no sigh of element ruthenium or anatase titanium dioxide,and the geometrical coating configuration is a perfect retile structure; When it is 25%,duration of anode is the longest.If taking the performance and cost of coating Ti anode into consideration,the most suitable mol percentage of Ru was 25%.Suitable sintering temperature was the key process means.The crystal grain growed incompletely in too low temperature,while the coating crack increased and the crystal grain growed too big in too high temperature.
