Herein, an efficient CuO QDs/TiO/WO photoanode and a Cu doped CoS/NiS cathode were successfully synthesized. The optimized CuO QDs/TiO/WO photoanode achieved a photocurrent density of 1.93 mA cm at 1.23 RHE, which was 2.27 times that of a WO photoanode. The CuO QDs/TiO/WO-buried junction silicon (BJS) photoanode was coupled with the Cu doped CoS/NiS cathode to construct a novel photocatalytic fuel cell (PFC) system. The as-established PFC system showed a high rifampicin (RFP) removal ratio of 93.4% after 90 min and maximum power output of 0.50 mW cm. Quenching tests and EPR spectra demonstrated that ˙OH, ˙O and O were the main reactive oxygen species in the system. This work provides a possibility to construct a more efficient PFC system for environmental protection and energy recovery in the future.
在此，成功合成了一种高效的CuO量子点/TiO/WO光阳极和一种铜掺杂的CoS/NiS阴极。优化后的CuO量子点/TiO/WO光阳极在1.23 RHE时实现了1.93 mA cm的光电流密度，是WO光阳极的2.27倍。将CuO量子点/TiO/WO埋入式结硅（BJS）光阳极与铜掺杂的CoS/NiS阴极耦合，构建了一种新型光催化燃料电池（PFC）系统。所建立的PFC系统在90分钟后显示出93.4%的高利福平（RFP）去除率和0.50 mW cm的最大功率输出。猝灭试验和电子顺磁共振光谱表明，˙OH、˙O和O是系统中的主要活性氧物种。这项工作为未来构建更高效的用于环境保护和能量回收的PFC系统提供了可能性。
