| 中文摘要 | 燃料電池藉由陽極產生電子,以提供陰極光電-芬頓系統之驅動力,其可達到汙染物礦化暨系統自保持之目的。本研究擇取碘氧化鉍(BiOI)光觸媒修飾陰極電極,透過光偕同反應提升系統羥基自由基(.OH)生成能力,惟單一光觸媒將面臨電子-電洞迅速重組之問題,導致系統催化表現遭受篏制。異質結(Heterojunction)建構為改善電荷復合率有利方法之一,本研究藉由水熱法耦合不同重量百分比之氧化亞銅(Cu_2O),形成BiOI/Cu_2O異質結,並採用電泳沉積法被覆於SS316L基材表面,藉以進行系統催化效益研析。顯示,異質結建構具有較低光致發光強度,代表催化過程有助於光生電荷參與化學反應,同時以(10 %)Cu_2O/BiOI/SS316L複合電極相較於SS316L基材,其染劑脫色效能提升約3.37倍,證實異質結建構有助於燃料電池系統效能強化,具未來深入研究之潛力。 |
| 英文摘要 | Electrons are generated at the anode of fuel cells. The electrons energize the cathode photoelectric-Fenton system, facilitating pollutant removal and system operation. This study employs bismuth oxyiodide (BiOI) photocatalyst-modified cathode electrodes to enhance hydroxyl radical (.OH) production through a synergistic photoreaction. However, an individual photocatalyst meets rapid recombination of electron-hole pairs, impeding catalytic efficiency. Constructing heterojunctions is an effective strategy for reducing charge recombination rates. This study combines various weight proportions of cuprous oxide (Cu_2O) with BiOI using a hydrothermal method to create BiOI/Cu_2O heterojunctions. The heterojunctions are subsequently coated on SS316L substrates through electrophoretic deposition to evaluate the catalytic performance of the system. The results show that heterojunction construction exhibits lower photoluminescence intensity, indicating the enhanced participation of photogenerated charges in chemical reactions. The composite electrode (10%)Cu_2O/BiOI/SS316L had a dye decolorization efficiency approximately 3.37 times more than that of the SS316L substrate, indicating that heterojunction construction substantially improves fuel cell system performance, necessary for further investigation. |
