用于光生阴极保护的ZnIn2S4/TiO2纳米管复合膜光阳极的制备方法
Abstract:
本发明公开了一种用于光生阴极保护的ZnIn2S4/TiO2纳米管复合膜光阳极的制备方法，制备方法，包括如下步骤：1)以抛光、清洗后的钛基体为阳极，以铂为对电极，在NH4F的乙二醇水溶液中进行阳极氧化后，煅烧，即在钛基体表面制得TiO2纳米管阵列膜；所述NH4F的乙二醇水溶液中，NH4F、水和乙二醇的质量比为2：20-30：400；煅烧的温度为450-550℃，煅烧的时间为1-2h；2)将Zn(NO3)2·6H2O，InCl3·4H2O和C2H5NS溶于水中得到混合溶液，将步骤1)中制备的TiO2纳米管阵列膜浸入混合溶液中，封装后煅烧，得到ZnIn2S4/TiO2纳米管复合膜。该方法制备的ZnIn2S4/TiO2纳米管复合膜具有良好的光电转化性能。
Abstract(English):

The invention discloses a preparation method of a ZnIn2S4/TiO2 nanotube composite membrane photoanode for photocathodic protection. The parathion method comprises the following steps that 1) calcination is performed by taking a polished and cleaned titanium substrate as an anode and platinum as a counter electrode after anodizing in NH4F ethylene glycol water solutions, namely that TiO2 nanotube array membranes are prepared on the titanium substrate surface; the mass ratio of NH4F, water and ethylene glycol is 2:20-30:400 in the NH4F ethylene glycol water solutions; the calcination temperatureis 450-550 DEG C, and the calcination time is 1-2 h; 2) Zn(NO3)2.6H2O, InCl3.4H2O and C2H5NS dissolve in water to obtain mixed solutions, and the TiO2 nanotube array membranes prepared in the step 1)are immersed in the mixed solution; and the calcination is performed after sealing, so that ZnIn2S4/TiO2 nanotube composite membranes are obtained. The ZnIn2S4/TiO2 nanotube composite membranes prepared with the method have excellent photoelectric conversion performance.
