Corrigendum to “Surface embellishment accelerates the oxygen evolution reaction and removal of organic pollutant using solvothermally designed Co₂O₃/CuO nanocomposite” [Volume 40, August 2023, 103019](S2468023023003899)(10.1016/j.surfin.2023.103019)

The authors regret <Following a comprehensive post-publication review of our manuscript, we have identified some instances where the data presented in specific figures were subjected to processing operations that may have altered their original appearance. We would like to issue this corrigendum to ensure full transparency and to provide the corrected, unprocessed versions of the affected data figures. Firstly, in Figure 1 (a–b), which displays the X-ray Diffraction (XRD) and Fourier-Transform Infrared (FTIR) spectra, the data were processed using OriginPro software. Specifically, we had applied baseline correction and smoothing functions to enhance visual clarity. However, upon further inspection, we recognize that these operations introduced slight deviations from the raw data, potentially impacting accurate interpretation. We have now replaced the processed spectra with the original, unprocessed data to preserve the authenticity and integrity of the presented results. In Figure 2(a), which presents the X-ray Photoelectron Spectroscopy (XPS) survey spectrum, a similar issue occurred due to baseline correction applied during data processing. This led to a minor deviation in peak presentation that could be misleading for readers. We have therefore updated the figure with the original survey spectrum without any post-processing adjustments to maintain the accuracy of elemental identification and spectral analysis. A more correction pertains to Figure 4 (a–c), which includes the Energy Dispersive X-ray Spectroscopy (EDS) spectra. It was discovered that incorrect labels were attributed to material under study, along with axis error, by a student during data compilation. We deeply regret this oversight and have now replaced figure with correct, original EDS data relevant to material discussed in the manuscript. Lastly, Figure 10(e), which illustrates XRD patterns before and after stability testing, also underwent data processing through OriginPro software. While the "before" stability spectrum was partially retained in its raw form, the "after" stability spectrum had undergone both baseline correction and noise reduction. These modifications unintentionally introduced discrepancies in peak appearance. To rectify this, we have now presented both the "before" and "after" XRD data in their original, unprocessed states for improved clarity and accuracy. We wish to emphasize that none of these corrections affect the scientific findings, interpretations, or conclusions of our study. The core results and their implications remain valid and unchanged. Moreover, no revisions to the main text of the manuscript are required as a result of these updates. We sincerely apologize to the editors and the readership of Surfaces and Interfaces for any confusion or inconvenience these errors may have caused. We remain committed to maintaining the highest standards of scientific transparency and integrity. >. The authors would like to apologise for any inconvenience caused.
