26. The fluctuation in Figure 2b is due to the low intensity (low signal-to-noise ratio) of sulfur as a light element in the EDX analyses but not to the actual variation of the loading amount of SiOPS.
27. The first weight loss step was assigned to the evaporation of water absorbed by the sulfonic acid groups of SPI. See Ref. [8a].
28. The higher water-holding capability of SiOPS compared to that of SPI is thermodynamic as the TG curves are independent of the heating rate.
