Solar hydrogen peroxide production and As(Ⅲ) oxidation using carbon electrodes wired to Titania nanorods arrays |
| 초록 |
A stand-alone photoelectrochemical cell composed of electrocatalytic H2O2 production using carbon electrode and hydrogen-treated TiO2 nanorod (h-TNR) arrays catalyzing the oxidation of As(III) to As(V) under simulated solar light. Loading CNT onto carbon paper enhances the catalytic performance and the Faradaic efficiency (FE) approaches ~100%. To drive the HPR, the 2-electron oxidation of As(III) to As(V) that accompanies the production of the proton/electron couples is achieved at an FE of ＞80% using the h-TNR arrays. The electrodes pair maintained high FE for both anodic and cathodic reaction over 10 h. In the case of PV-cell coupling, electrodes pair successfully drives the standalone operation of both reactions at the high FEs (＞90%). This research was supported by the Basic Science Research Program (2019R1A2C2002602 and 2018R1A6A1A03024962) and the Technology Development Program to Solve Climate Changes (2019M1A2A2065616) through the National Research Foundation, Korea. |
