Table 3: Porosity results for all samples. of them are formed at lower temperatures [45], and any modified sample has a higher percentage of micropores than the blank sample (system 60_0.5) with less AsA. When the system is at the same temperature and higher AsA (60_2), higher percentages of micropores are observed for the cases of TMOS and TMOSN. The same behavior is observed for all modified samples at 90 \({}^{\circ}\)C. At lower AsA concentrations, all modified samples displayed fewer micropores and smaller pores than the system at 60 \({}^{\circ}\)C. In the case of sample 90_2, the percentage of micropores for the modified samples is slightly higher than the blank one. Finally, the resulted porosity (Table 3) is verified from the d\({}_{\text{p}}\) changes of the modified samples. The only system that shows the most significant change in average porous diameter is the 90_2. All modified samples showed a bigger diameter with an average of 163 A increase, which is 31% compared to the blank (124 A). For the rest of the systems, a slight increase is found except for rGO with TMOS. In the case of 60_2, on average, there is a decrease in the average porous diameter from 141 A to 136 A from two modified samples, and the only sample with TMOSN shows a little bit bigger diameter. This is in accordance with the increased microporous percentage for these systems (as observed before). The system at 90_0.5 has a slight increase (140 A to 141 A) only because of the two modified samples except for TMOS. In conclusion, based on modification, the highest increase was observed for samples with TMOSN 27% (171 A compared to 135 A for the blanks), then for the TMON 7% (145 A vs. 135 A) and the samples with TMPOS, a decrease in the d\({}_{\text{p}}\) was observed \(-4\%\) (129 A vs. 135 A). In Figure 7, an illustration of all monolithic samples can be seen. This illustration is based on the SA, the percentage of micropores compared to the whole volume of the pores, and the average pore diameter. The differences among all the values for the blank sample can be seen compared with the modified ones, especially for the SA and the percentage of the micropores compared to the total pore volume. All analogous illustrations for all monoliths for SA and micropore percentage are derived from the initial values of the sample rGO60_0.5. Figure 6: Micropores percentage for all samples and for all preparation parameters and modifications. Labels of B, N, S, and SN represent the blank system, systems modified with TMON, systems modified with TMOS, and systems modified with TMOSN, respectively. The formation of the porous network is a pretty complicated procedure that is not affected only by AsA quantity and temperature of reduction. It is true that AsA and temperature are playing an important role, but not the only one.
