Reviewer 3 Report
S.R. Pradhan et al presented the following manuscript entitled as ‘’ Bimetallic TiO2 Nanoparticles for Lignin-Based Model Com[1]3 pounds Valorization by Integrating Optocatalytic Flow-Micro-4 reactor.
Authors synthesize bimetallic TiO2 nanomaterial using Au with Cu and Fe with the ratio (1:4) using Cupper acetate, cupper nitrate and iron nitrate precursor. New scientific approach to use PFA and its inner surface modification with CuA-Au/TiO2, CuN-Au/TiO2 and FeN-Au/TiO2 nanomaterial. Obtained data are promising. This manuscript needs to explain the following queries before consideration.
Introduction:
1- Line 29: Sentence must not start with ‘Because’. Need to revise the sentence and start with proper background of TiO2 material.
2- Line 46-48, ‘As is well known, bimetallic catalysts show tunable and synergistic effects for conventional heterogeneous catalysis compared to their monometallic counterparts.’ It is in need to revise.
3- Need to include some crude data finding in Abstract and introduction.
Material and Method:
1- In material, please add the city and county for each chemical.
2- In catalytic synthesis section: Why did the authors choose Au: Cu and Fe (1:4) and isopropanol?
3- In in microreactor preparation section: Why was PFA 0.8 mm choose in term benefit for this study?
4- PFA pipe usually somehow opaque, as bimetallic nanoparticles were coated inside the PFA tube it will enhance. How did UV-Vis light pass through the tube (as being opaque) and bi-metallic TiO2 work as photocatalyst?
5- What are the possibilities for the conversion CuO or Fe2O3 or Fe3O4 nanostructure with Au/TiO2 nanoparticles as samples were heated at 80 0C ?
Results and discussion:
1- In Figure 2(a), CuA-Au/TiO2 nanomaterials shown high conversion while CuN-Au/TiO2 lower. However, initially conversion % was same.
2- XRD data is not interpreted and Fig. 3(a) is not mentioned in the text?
3- Need to include the recyclability of each system.
4- One comparative table with literature should include in the manuscript.
Conclusion:
Conclusion must revise and improvise with core finding data.
