- 摘要:
- 随着人们对海洋资源的不断开发利用，水下传感器的应用越来越广泛。然而水下传感器的光学窗口极易受海洋生物污损的影响，从而导致采集的数据严重失准。为更好地解决水下光学窗口的生物污损问题，采用电化学恒电位电解方法，在导电玻璃 ITO 上，制备了对电解海水析氯反应具有高效催化作用的 Co （ OH ）2 涂层。结果表明：电解析氯产生的次氯酸是一种良好的杀菌剂，对海洋中的污损生物具有很好消杀作用。在质量分数 3.5% 的氯化钠溶液中，所制备催化剂涂层的催化活性、选择性和耐久性均优于传统的贵金属催化剂，且成本较低。与导电玻璃 ITO 相比，沉积有催化剂涂层的导电玻璃 ITO 能够有效抑制藻类在光学窗口的附着和生长，有助于保持光学窗口的高透光率。该方法为海洋光学传感器的防生物污损提供了有益的策略。
- Abstract:
- ： With the continuous development and utilization of marine resources ， the application of underwater sensors is more and more extensive. However ， the optical window of the underwater sensor is easily affected by marine biofouling ， resulting in serious misalignment of the collected data. In order to better solve the problem of biological fouling of underwater optical window ， Co （ OH ） 2 coating with high catalytic effect was prepared on conductive glass ITO by electrochemical potentiostatic electrolysis. The results show that the hypochlorous acid produced by electrolyzed chlorine is a good bactericide and has a good biocidal effect on marine fouling organisms. In 3.5 wt%NaCl solution ， the catalytic activity ， selectivity and durability of the prepared catalyst coating are better than those of traditional precious metal catalysts ， and the cost is lower. Compared with conductive glass ITO ， conductive glass ITO deposited with catalyst coating can effectively inhibit the attachment and growth of algae in the optical window and help maintain the high transmittance of the optical window. This method provides a useful strategy for the anti-biofouling of marine optical sensors.
