对表面粗糙度不同的钛(Ti)基体进行抛光和喷砂处理,通过H2IrC16和Mn(NO3)2水溶剂在处理后的基体上制备IrO2+ MnO2涂层.采用扫描电子显微镜(SEM),场发射扫描电子显微镜(FESEM),循环伏安法(CV)和阳极极化曲线研究了不同表面粗糙度的IrO2+MnO2涂层的表面特性,结构和电催化活性.在所有通过喷砂处理的基体表面上制备的IrO2+MnO2涂层中,都可以分离出二氧化铱纳米棒,但通过抛光处理的涂层不能形成.通过喷砂处理的IrO2+MnO2涂层的qT,q.,qi和i/qT值远远高于抛光处理的涂层.表面粗糙度为1.3 μm的IrO2+MnO2涂层比其他涂层具有更好的电催化活性.
