Reviewer 2 Report
In this manuscript nickel based catalysts supported on silica from bagasse ash are studied for photothermal dryforming of methane with an aim of low-temperature reaction. The obtained catalyst samples are characterized using XRD, N2 adsorption, SEM, XRF, UV-Vis spectra and photothermal catalytic activity evaluation. 3%Ni/SiO2 BA shows higher hydrogen yield at 300 °C.
Several questions are as follows.
1 Table 1, extracted SiO2 shows high surface area than commercial SiO2. But commercial SiO2 can possess as surface area as several hundred m2/g. Why commercial SiO2 with 10.7 m2/g is used.
2 Table 2, the concentration of Ni of Ni/SiO2 BA WI is 11.7%, for which sample, which is far higher than that of either 3%Ni/SiO2 BA or 5%Ni/SiO2 BA.
3 Figure 6, what are the reaction times for the data. And Figure 6(d), why does the CH4 conversion decrease as the temperature rises, which is thermally catalyzed or photocatalyzed or photothermally catalyzed? A controlled experiment at heating but without light irradiation is needed.
4 Lines 276-281, are the catalyst samples reduced before reaction? If not, how do they thermally catalyze the reaction.
The expression is acceptable.

Reviewer 2 Report
The initial manuscript was reviewed on May 2. Four suggestions were given for reference, which are not explained in this manuscript. In addition, Figure 1 provided is not mentioned in the body. So, the experiumental data obtained by the authors are not corresponding well to the title.
