Photocatalytic Properties of Silver Nanospherical Arrays Driven by Surface Plasmons
Round 1
Reviewer 1 Report
The author's research has realized the drawing and erasure of molecular graphics at micro/nano level, and the information encryption, reading and erasure with strong application value. It has some novelty and a rigorous writing, but I would suggest making some changes before publication.
- Some formatting issues need attention, such as section 3, paragraph 6, line 4.
- Experimental articles suggest adding error analysis.
- As for the selection of spectrum, why the light of 633nm is selected for detection?Is there any particular reason?
- Why should sodium borohydride be introduced in situ? What is the significance of doing so?
- As for Fig.3, 2s is not clearly marked in the figure..6s.8s?
- Carefully check the ordinate of Fig.3 b and d and the ordinate annotation of Fig.4 c.

Re: Thank you very much for your review and good suggestions. According to your suggestions, I have modified the manuscript.
1.Some formatting issues need attention, such as section 3, paragraph 6, line 4.
Re: It has been modified in the manuscript.
2.Experimental articles suggest adding error analysis.
Re: The error bars are inserted in Fig 3 (c) and (d).
3. As for the selection of spectrum, why the light of 633nm is selected for detection?Is there any particular reason?
Re: With the help of Raman fingerprint spectroscopy, the reaction state of probe molecules and products can be monitored synchronously and in real time. The excitation wavelength of Raman spectrum is limited by the hardware technology of the instrument, and can only use several specific wavelengths, such as 633 nm.
4. Why should sodium borohydride be introduced in situ? What is the significance of doing so?
Re: Under the same experimental conditions, the photocatalytic reverse reaction can be realized by introducing sodium borohydride as reducing agent.
5. As for Fig.3, 2s is not clearly marked in the figure..6s.8s?
Re: It has been modified in the manuscript.
6. Carefully check the ordinate of Fig.3 b and d and the ordinate annotation of Fig.4 c.

Reviewer 2 Report
The manuscript submitted by Zhang et al. describes the use of SERS spectroscopy to record the photocatalytic conversion of p-aminothiophenol into dimercaptoazobenzene on a silver hemispherical nanoarray. I recommend its publication in Chemosensors after Minor Revision.
- The authors should reorganise the introduction to make it more fluent and include (or reorganise) references to support the written statements.
- Very similar studies as e.g. DOI: 10.1021/acs.jpcc.0c01367, DOI: doi.org/10.1002/cctc.201600172, DOI: 10.1016/j.apcatb.2017.10.009, DOI: 10.1016/j.saa.2016.04.046, DOI: 10.1039/C0CC05302C, should be included and discussed. The authors should also discuss the advantages of the proposed method over those already published.
- The word SERS or Raman is misused in several places.
- In the last paragraphs of the introduction, at the end of the manuscript and in the conclusions, the authors state that their method can be used to draw Chinese characters. However, this is based on speculations, as they do not include any evidence that this is indeed possible.
- The authors should include specific details about the silver deposition, identically to what they have done for the aluminium nanoarray fabrication.
- Details about the objective, acquisition time, number of accumulation should be included in section 2.2. Acquisition of Raman spectrum.
- I recommend the authors combine Figure 1a and 1b to make the comparison between peaks easier.
- Blue spectra in Figure 1b represents the Raman spectrum of DMAB. How was the spectrum taken? Solid powder as PATP, in solution?
Minor comments:
- Line 18. Replace gold nanoarrays with silver nanoarrays.
- The abbreviation SPS was not introduced.
- Line 40. SERS can enhance the weak Raman signal by 105-108. I think the authors mean 105-108. A reference is needed here.
- Please correct with the correct units 6 W% and 1.8W% in line 98.
- Why was 1 mW laser power used to record the SERS spectra
- Figures 2b and 3d, include the number of repetitions.

The authors should also discuss the advantages of the proposed method over those already published.
Re: Thank you very much for your good advice. This manuscript first reported the photocatalytic reaction performance based on silver nano arrays, and then introduced sodium borohydride as reducing agent to realize the photocatalytic reverse reaction under the same experimental conditions.

Re: After preliminary exploration experiments, it is concluded that the 1 mW laser power the requirements of this experimental system.
6. Figures 2b and 3d, include the number of repetitions.
Re: Thank you very much for your advice. The ‘Y error bar’ in the Figures 3b and 3d comes from the ‘Single Peak Fit’ Standard Error parameters of the SERS peaks located at 1142 and 1080cm-1 in the Figures 3a and 3c. So, each Standard Error value comes from the intensity information of a SERS line.
Reviewer 3 Report
1) In Line 33 and 35 the abbreviation SPS is not explained in text
2) Line 40 enhancement of week Raman signal is probably 105-108 not 105 -108
Author Response
The two amendments mentioned above have been revised in the manuscript. The details are as follows:
1. In line 28 : Surface plasmons (SPS) originate from the collective oscillation of conduction electrons and play an important role in the optical properties of nanostructured metals and heavily doped semiconductors.
2. In line 40 : The superscript format has been modified for 105-108.
