Grain Boundary Regulation in Aggregated States of MnOx Nanofibres and the Photoelectric Properties of Their Nanocomposites Across a Broadband Light Spectrum
Round 1
Reviewer 1 Report
Comments and Suggestions for Authors· Provide current–voltage (I–V) and current–time (I–t) curves under different light wavelengths and intensities to better analyze the optoelectronic behavior.
· Present data for pure MnOx and pure GO samples to clearly isolate and understand the effect of the nanocomposite structure.
· Improve the quality and clarity of all figures. For example, in Figure 2 (XRD results), add crystal plane orientations to better interpret the phase identification.
· For XRD, SEM, and XPS figures, clearly label and discuss both composite samples (e.g., samples with 10% and 30% GO content).
· Contextualize the results by comparing your findings with recent literature on MnOx/GO-based photodetectors. Discuss how your performance compares with previous studies in terms of sensitivity, stability, or wavelength range.

Reviewer 2 Report
Comments and Suggestions for AuthorsThe current manuscript reports the preparation of MnO2/GO composites and their potential applications in optoelectronic devices. In this work, the authors attempted to enhance the photophysical properties of MnO2 by adding a GO matrix. The obtained samples were characterized to obtain structural and morphological information. The samples were designed as a sensor to be useful in chemical and photoelectric signal detection. Overall, the manuscript is suitable for publication after the following revisions.
- The introduction part should contain details such as the importance of heterostructures in optoelectronic devices.
- Each data should be compared with that of bare MnO2 and MnO2/GO
- The detailed charge transfer or separation in MnO2?GO should be considered.
