As a widely used antimicrobial agent in toothpastes and body washes for decades, triclosan (TCS) is causing great harm to the environment through wastewater. Herein, we used a two-electrode system to remove TCS comprising Co₃O₄ nanowires/carbon cloth (Co₃O₄ NWs/CC) as anode and CoP nanowires/carbon cloth (CoP NWs/CC) as cathode. At a constant current density of 10 mA cm⁻², the degradation efficiency for TCS is 95% in 60 min and it is transformed into important chemical raw materials, including phenol, 1,2-dihydroxybenzene, and 2-phenoxyphenol. Subsequently, hydrogen is generated on the CoP NWs/CC cathode with Faradaic efficiency of nearly 100%. The synergetic effect of the superhydrophilic surfaces of the Co₃O₄ NWs/CC anode and the CoP NWs/CC cathode as well as the superaerophobicity of the cathode assures full contact of the electrolyte solution and the active materials and high-efficiency generation of H₂ bubbles.

作为数十年来在牙膏和沐浴露中广泛使用的抗菌剂，三氯生（TCS）通过废水对环境造成了极大的伤害。在这里，我们使用两电极系统去除TCS，其中包括Co ₃ O ₄纳米线/碳布（Co ₃ O ₄ NWs / CC）作为阳极，CoP纳米线/碳布（CoP NWs / CC）作为阴极。在10 mA cm ^-2的恒定电流密度下，TCS的降解效率在60分钟内达到95％，并转化为重要的化学原料，包括苯酚，1,2-二羟基苯和2-苯氧基苯酚。随后，在法拉第效率接近100％的CoP NWs / CC阴极上产生氢。Co的超亲水表面的协同作用₃ O ₄ NWs / CC阳极和CoP NWs / CC阴极以及阴极的超疏水性确保了电解质溶液和活性材料的充分接触，并确保了H ₂气泡的高效生成。
