Correction: Development of composite catalyst containing renewable biochar blended with zinc oxide and copper diphenyl amine for visible light photocatalytic degradation of methylene blue (Frontiers in Sustainable Food Systems, (2025), 9, (1500907), 10.3389/fsufs.2025.1500907)

In the published article, there was an error in the legend for Figure 2 as published. Figure 2, lacks the permission license number (6016250857795), which has been reused from the source “Physica E: Low-dimensional Systems and Nanostructures ”. Authors apologizes for this overlook during manuscript preparation. However, declare that by such insertion of license number, the conclusion will not be altered altogether. The corrected legend appears below. “Figure 2. SEM micrographs of (A) ZnO at mag 5.00 K X, (B) Cu-DPA composite at mag 10.00 K X. copyright 2025 by Elsevier.
