| 제목 | Sunlight-induced photoelectrocatalytic wastewater treatment and hydrogen production coupled with desalination by reduced titania nanorods and Ni-Mo-S catalysts |
| 초록 | The desalination of brackish water in the desalination cell is initiated via photoinduced charge generation with a thermochemically reduced TiO2 nanorod array photoanode. The chlorides transferred to the neighboring anolyte at ion-transport efficiency of ∼100% are photoelectrochemically transformed into reactive chlorine species responsible for the decomposition of urea into nitrate in the anolyte. Simultaneously, the H2 production with a Ni–Mo–S (Ni2S3/MoS2) composite catalyst grown onto porous Ni substrate is achieved at Faradaic efficiency of ∼90% in the catholyte concentrated with desalted Na+. This study has been conducted with the support of the National Research Foundation of Korea (2019R1A2C2002602), and the Ulsan Metropolitan City as “Development of Carbon Dioxide Capture and Utilization Technology for Greenhouse Gas Reduction”(U201900107). |
