摘要:

在55℃的1.0~10.0 mol∙L−1 NaOH溶液中,通过10 mA∙cm−2恒电流阳极氧化和空气中150℃热处理,在黄铜基底表面制备出具有纳米颗粒或纳米片形貌的铜氧化物薄膜。利用XRD、SEM和Raman光谱等分析了氧化膜的结构和形貌。在0.1 mol∙L−1 Na2SO4溶液中测试了氧化膜在零偏压下的可见光光电流。结果表明,黄铜在3.0~5.0 mol∙L−1的NaOH溶液中经阳极氧化,可制备出具有纳米片形貌的Cu2O/CuO复合氧化物薄膜,在零偏压下的光电流密度分别为1.9和1.4 μA∙cm−2

Copper oxide films with nanoparticles or nanosheets morphologies were prepared on the surface of brass substrates through anodic oxidation of the brass at 10 mA∙cm−2 in 1.0 - 10.0 mol∙L−1 NaOH solutions, at 55˚C, then heated at 150˚C in air. The structures and morphologies of the oxide films were analysed with XRD, SEM and Raman spectroscopy. The photocurrents of the films were tested in 0.1 mol∙L−1 Na2SO4 solution under a visible light and zero bias. Results show that nanosheet CuO/Cu2O composite films can be obtained by anodic oxidation of the brass in 3.0 - 5.0 mol∙L−1 NaOH solutions, and the films generate the photocurrents of 1.9 and 1.4 μA∙cm−2, respectively, at zero bias.
