Heterogeneous alloyed CuSnO-DopaCube mediated photo-Fenton and photothermal synergistic catalysis for dye elimination
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 Cu 2 O-SnO 2 -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 Cu 2 O 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 through the synergistic effect of photocatalysis and photothermal processes.
