Abstract
The Fenton/Fenton-like reaction is of significant importance in biomedical and environmental remediation applications. However, the use of Fenton/Fenton-like catalysts is limited due to incomplete light absorption, low energy conversion efficiency, and a narrow pH range. To address these issues, we have developed a photothermal-driven heterogeneous Fenton system using Cu2O-SnO2-Polydopamine (PDA) triple cubic heterostructures, which exhibit strong photothermal capabilities in the NIR region. The macromolecular PDA acts as a heat source for higher degradation efficiency due to its excellent photothermal conversion performance. Furthermore, our results show that the system significantly improves the energy conversion efficiency of Cu2O and exhibits excellent catalytic activity over a wide pH range by using Rhodamine B (RhB) as the model dye. This study offers a novel approach for environmental remediation thro
