Light-driven O₂ reduction reaction is regarded as a green and simple approach for H₂O₂ production in contrast with the industrial process. Along these lines, CdS nanorods (CdS NRs) were fabricated by the solvothermal method and modified by MoS₂ in this work. From the Kelvin probe measurements, the existence of a built-in electric field (BEF) was demonstrated. The electric field that was developed at the interface between CdS and MoS₂ could elevate the separation efficiency of the photo-induced electron-hole pairs, ensuring a high photocatalytic H₂O₂ production performance. Moreover, the incorporation of MoS₂ provides a much larger active area and improves the stability for long-time utilization. The CdS NRs/MoS₂ composites also display especially improved capacities for the efficient photocatalytic H₂O₂ production with 1350 μM h⁻¹. A novel and feasible strategy is introduced to enhance the photocatalytic H₂O₂ production activity of CdS NRs, which will be beneficial to H₂O₂ evolution in actual applications.

与工业过程相比，光驱动的O ₂还原反应被认为是一种绿色且简单的H ₂ O ₂生产方法。沿着这些思路，在这项工作中，CdS 纳米棒 (CdS NRs) 通过溶剂热法制造并通过 MoS ₂进行改性。通过开尔文探针测量，证明了内置电场 (BEF) 的存在。_{在 CdS 和 MoS 2}之间的界面处形成的电场可以提高光生电子空穴对的分离效率，从而确保高光催化 H ₂ O ₂生产性能。此外，MoS _2的加入提供更大的活动区域并提高长时间使用的稳定性。CdS NRs/MoS ₂复合材料还显示出特别改进的高效光催化 H ₂ O ₂生产能力，1350 μM h ^-1。引入了一种新颖可行的策略来增强 CdS NRs 的光催化 H ₂ O ₂生产活性，这将有利于实际应用中的 H ₂ O ₂释放。
