Summary: Underwater optical instruments are often affected by biofouling. Electrochemical chlorination is an effective antifouling strategy, but its limited activity and selectivity restrict its practical application. This study focuses on optimizing the chlorine evolution reaction (CER) performance of cobalt-based catalysts. The results show that α-Co(OH)2 exhibits better CER performance than β-Co(OH)2, and the manipulation of α-Co(OH)2 morphology further enhances the CER performance. The findings not only enhance our understanding of synthetic conditions on CER performance but also provide insights into the development of electrochemical antifouling strategies.

Summary: The reflective-matched FBG is an interrogation method that realizes automatic temperature compensation but has a small measurement range. A range extension method has been proposed to extend the measurement range while maintaining system sensitivity. In the experiment, the system's performance with different bandwidth sensors and filters was studied, achieving a maximum strain sensitivity of 0.261 mV/mu epsilon. After range extension, the sensitivity remained at 0.248 mV/mu epsilon. The temperature compensation capability of the system was also confirmed, with temperature effects reduced to 7.8% of the uncompensated system.
