Reviewer 1 Report
The authors have designed and synthesized novel defective Bi@Bi3NbO7 structures with good porosity were fabricated by a solvothermal method and used for photocatalytic NO removal under visible light irradiation. The morphological and structural properties of the prepared materials were comprehensively analyzed. However more discussions and data are necessary to make the manuscript clear. Therefore, this manuscript can be published after major revision.
1. This paper mentions that the appropriate amount of urea and bismuth have excellent photocatalytic properties. If the content of the Bi added is too large, what is the effect on the pore?
2. What parameters are fixed for the xenon lamp used in the article? Is it the optical power density?
3. Will the phase and morphology of the catalyst change after the stability test? Therefore, it is recommended that the author perform morphological characterization for catalyst such as XRD and SEM.
4. There are some issues which require thorough proof reading. All the drawings are not clear, the icon position is not uniform, the word size is not uniform.
5. In Figure 3a, why does C/C0 of BNO increase after 11 minutes. In Figure 3b, 4% Bi-2-BNO increase after 9 minutes?
6. The size of the illustration in Figure 6b is too large, so the same size of the illustration in 6a can be provided.
7. Figure 7a can put an illustration, the current figure cannot see the effect.

Reviewer 2 Report
Wang et all reported synthesis of porous defective Bi@Bi3NbO7 nanosheets and utilized them as efficient visible light active photocatalyst for removal of NO. Optimum loading of plasmonic Bi nanoparticles and presence of porous defects in nanosheets synergistically leads to the better light harvesting capacity and charge carriers separation. Presentations of scientific explanations are well supported by the experimental data. This research article could be very attractive to large number of audience; therefore I recommend this articles acceptance after following minor modifications:
(1) In this paper author highlighted utilization of Bi as a cheap plasmonic materials alternative to expensive noble metals. Hence, I recommend these references to add in the introduction section on other available cheap alternative plasmonic materials such as Al (ACS Nano 2022, 16, 4, 5839–5850) and TiN (Nano Energy 2022, 104, 107989).
