Three-dimensional cubic ordered mesoporous carbon with chitosan (Ia3d-CS), which was synthesized via exothermic reaction between liquid potassium and carbon monoxide gas, was coated on the active carbon (AC) electrode as a capacitive deionization (CDI) disinfection electrode. The results showed that Ia3d-CS-2 as CDI electrode exhibited the quick ion diffusion and strong charge transfer performance, due to the three-dimensional pore structure and specific surface area. The electrode of Ia3d-CS-2 displayed a specific capacity of 191.22 F/g at a scan rate of 100 mV·s-1 in 0.5 M NaCl aqueous solution. In a CDI recycling system, Ia3d-CS-x electrode showed good cyclic stability, and the electrosorption capacity of Ia3d-CS-2 electrode can achieve 1.31 mg/g at 1.2 V in 100 mg/l NaCl aqueous solutions. Subsequently, Ia3d-CS-2 electrode had an excellent disinfection efficiency of killing about 99.99% Escherichia coli within 30 min during the CDI process at applied 1.2 V. Considering those excellent properties of the fabricated Ia3d-CS-x electrode, which should be a better candidate for high-performance deionization application.

带有壳聚糖的三维立方有序介孔碳，用于水的电容去离子消毒。

通过液态钾和一氧化碳气体之间的放热反应合成的具有壳聚糖的三维立方有序介孔碳（Ia3d-CS）被涂覆在活性炭（AC）电极上，作为电容去离子（CDI）消毒电极。结果表明，由于三维孔结构和比表面积，作为CDI电极的Ia3d-CS-2具有快速的离子扩散和强的电荷转移性能。Ia3d-CS-2电极在0.5 M NaCl水溶液中的扫描速率为100 mV·s-1时，显示的比容量为191.22 F / g。在CDI回收系统中，Ia3d-CS-x电极表现出良好的循环稳定性，在100 mg / l NaCl水溶液中，1.2a时Ia3d-CS-2电极的电吸附容量可达到1.31 mg / g。后来，
