Abstract：
Compared with traditional electrolytic technology, directly using photocatalytic materials to produce hypochlorous acid from chlorine-containing water undoubtedly has stronger low-carbon and environmentally-friendly characteristics. However, currently reported materials with photocatalytic chlorine production performance require precious metal Pt for catalysis, which undoubtedly greatly increases production costs. Therefore, developing new types of non-precious metal-based photocatalytic materials for efficient hypochlorous acid synthesis has significant implications. In this study, we demonstrate a novel breakthrough by showing that the WO3/CdS with a Z-scheme structure effectively generated 3.54 mg/L of free chlorine in a 0.5 M NaCl solution, while also exhibiting spectral bactericidal and algal inhibition properties. The Z-scheme structure can effectively prevent carrier recombination and improve photocatalytic efficiency. Therefore, this research provides a novel approach to photocatalytic antifouling and holds significant implications for the application of photocatalytic technology in the marine antifouling industry.
摘要：
与传统电解技术相比,直接利用光催化材料从含氯水中生产次氯酸无疑具有更强的低碳环保特性。然而,目前报道的具有光催化产氯性能的材料需要贵金属Pt进行催化，这无疑大大增加了生产成本。因此,开发新型非贵金属基光催化材料对次氯酸的高效合成具有重要意义。在这项研究中,我们证明了一个新的突破，通过显示WO3/CdS与Z-方案结构有效地产生3.54mg/L的游离氯在0.5MNaCl溶液，同时还表现出光谱杀菌和藻类抑制特性。Z-方案结构能有效防止载流子复合,提高光催化效率。因此,这项研究为光催化防污提供了一种新的方法，并对光催化技术在海洋防污工业中的应用具有重要意义。
