### Porosity Results  
We expected that different modifications would result in different rGO's monolithic structures, meaning differences in characteristics concerning the porosity and specific area. Porosity results show interesting changes in the specific area (SA) as measured through BET, the total volume of pores, percentage of micropores, and average pore size. Systems modified with different components, different analogies of AsA, and changing the temperature of monolith preparation can significantly affect the parameters mentioned above [8; 9]. Figure 5 and Table 3 reveal increment of SA for 9/12 modified samples compared with the initial ones. In system 60_0.5, all three modified monoliths showed higher SA with an average increase of around 237% compared with their corresponding blank. Similarly, in system 60_2, two out of three modified monoliths presented a 17% increase in SA compared with their corresponding blank sample. In system 90_0.5, all three modified monoliths had higher SA with an average increase of 52%. Finally, in the last system, 90_2, only one sample resulted in a higher SA (modified with TMON) while the general trend was a decrease of 5%. When we compared SAs based on the modification component, we observed that the average SA is 297 m\({}^{2}\)/g, 287 m\({}^{2}\)/g, 200 m\({}^{2}\)/g, and 189 m\({}^{2}\)/g for TMON, TMOS, TMOSN, and blank modified samples, respectively; therefore, all modifications led to an average increase of 57% (TMON Vs. Blank), 52% (TMOS Vs. Blank), and 6% (TMOSN Vs. Blank). Resulted SA values verified our previous observation by SEM imaging that different modifications affected the porosity of the monoliths. The biggest alterations in SA values were found for samples modified with TMON at low AsA quantity and 60 \({}^{\circ}\)C. Increment of SA value changes of the systems was as follows: 60_0.5 > 90_0.5 - 60_2 > 90_2. Furthermore, the total pore volume and the different micropores volume and analogies showed changes, depending on the different modifications and preparation parameters [43; 44]. The total pore volume as long as the different volumes for mesopores and micropores are shown in Table 3. In 60_0.5, the modified samples had increased pore volumes compared with the blank; displayed 5.4, 3.3, and 3 times more for TMON, TMOS, and TMOSN, respectively. An increment of the quantity of AsA (60_2) at the same temperature showed no significant effect on the whole pore volume. Just TMON modified monoliths displayed a small increment of the total pore volume. Similar behavior was observed for the samples modified at 90 \({}^{\circ}\)C. In the case where AsA is in less analogy (0.5), the total pore volume compared to the blank is increased 2.4 times (TMON), 2.1 times (TMOS), and 1.5 times (TMOSN). In addition, when AsA is increased to an analogy of 2, the total pore volume remains almost the same (1.1 times for TMON and TMOSN) and even less in just one case (TMOS). The results mentioned above regarding the range of the pore volume are shown in Figures S3 and S4. The whole range of pores in the cases where AsA is less, the cumulative pore volume is always higher for the modified samples at both temperatures (Figures S3 and S4). Interestingly, when AsA is at higher analogy (2), the changes are not so evident, and the pore range in terms of cumulative volume is quite similar. Based on these results, one crucial point that should be mentioned is that in the system 90_2 for all modified samples after 1000 A, a peak is detected, meaning that macropores start forming at these experimental parameters. In addition, from Figure 6 and Table 3 concerning the percentage of the micropores, more
