tib2基ruo2+tio2涂层的电催化性能*
Keywords: 复合材料,ti/tib基体电极材料,ruo-tio涂层,热分解法,电化学性能
Abstract:
？用磁控溅射法在钛基体表面溅射tib2中间层,以此为基体用热分解法制备了(ru,ti)氧化物涂层钛电极,用sem、xrd、电化学工作站等手段对样品的性能和结构进行了表征。结果表明,含tib2中间层的钛阳极表面涂层具有非连续状裂纹结构,钛基体和氧化物涂层的界面呈现紧密结合的状态,其电催化析氯性能优于传统钛阳极。选用tib2中间层作为催化电极的载体,可改善基体和氧化物涂层的结合,延缓涂层的脱落,可避免基体和涂层间生成tio2电阻膜,延缓涂层的失效;加入tib2中间层可降低内阻,改善电子的传输能力,降低析氯电位,提高电极的催化活性和节能降耗。
