Reviewer 2 Report
Pereira et al. presented an interesting manuscript on ?5+-doped ???2/??3 ??? nanostructures, describing both their preparation and application. The authors prepared three MMO samples - a mixture of T??2: ??3 (1:1 ) and a mixture of T??2: ??3 doped with different concentrations of V2O5, and presented a detailed analysis of the resulting structures using a number of techniques. In addition, Pereira et al. investigated the photocatalytic abilities of the resulting materials, using visible light photodegradation of Rhodamine B as an example. The submitted article is correct, and with minor corrections, I believe the article can be accepted for publication in the journal: Inorganics.
1. For photocatalytic testing, the authors used a continuous white light, with light output of 60W, located 30 cm from the reactor. Can the authors provide the type of light source? Did the authors measure the intensity of the light on the sample (reactor)? (Such a large distance of light from the sample causes additional effects, so it's hard to tell what light intensity was on the sample during the study).
2. In Figure 9, the authors compare the kinetics of photodegradation with MMO-loaded fibers. Can the authors explain the abbreviations used on the Y-axis in Figure 9 (C/C0)?
3.The authors stated: Especially, the increase in the doping level provided a lower pair recombination rate, as a consequence of the progressive decrease in the semiconductor band gap (as discussed previously) (line: 392-394). Although this statement is deduced from Figure 9, it would be helpful for a better description of the obtained results to quantify this recombination rate, by, for example, determining the slope of the curves presented in Figure 9 (one possibility is to determine dC/C0/dt, where d is the derivative). [The slope of the curve is directly proportional to the rate of degradation].

Round 2
Reviewer 1 Report
The authors addressed all my comments, and completed the recommended experimental work except one experiment; they claimed that the facility is not available in their lab. Thus, in my point of view, the manuscript is publishable in its current form.
