Or CH-HDTMA, respectively. For both SMZs, the N:C ratio was 0.03, which corresponds towards the worth obtained for the pure HDTMA. This demonstrates that the N and C presence around the zeolite surface originated in the modification course of action. Meaningfully, there was no presence of Br. The analysis from the dynamics of changes within the chemical composition permitted for any qualitative assessment with the distribution of components within the cross-section in the modified single layer. A diversified reduce in N:Si and N:Al ratios was observed along with Ar sputtering, which indicates that a few of the immobilized HDTMA was trapped within the pores and cavities of zeolitic material. To become additional precise, decrease lower observed in the case of CH (25 ) in comparison to CL (57 ) resulted from the more flattened surface with the latter. The lack of Br along with the evident shift of N 1s binding energy (for pure HDTMA, Figure 6e) to 402.eight eV (for each CLand CH-HDTMA, Figure 6a,b) affirm that HDTMA binding to the zeolitic surface happens by means of N .Components 2021, 14, 7061 Supplies 2021, 14, x FOR PEER REVIEW12 of12 ofFigure XPS N 1s and Al2p Br3d spectra for CH-HDTMA 1.0 ECEC, (b) (b) CL-HDTMA 1.0 ECEC, Figure 6.

Nonetheless, the difference in in N content material than for materials loaded with xx = 1.0 ECEC. Nonetheless, the differenceN content (as (as received) in between mono and double Thromboxane B2 References layers equaled 61 and 31 CL-HDTMA and received) between mono and double layers equaled 61 and 31 forfor CL-HDTMA and CH-HDTMA, respectively. This confirms partial HDTMA capture in in external pores CH-HDTMA, respectively. This confirms a a partial HDTMA captureexternal pores and and caves on external CH zeolite surface, which produced it tricky a a double layer to become caves on external CH zeolite surface, which made it difficult forfordouble layer to be formed formed there [22]. A lower in GS-626510 Cancer relative N/Si and N/Al ratios as well as Ar etching rethere [22]. A decrease in relative N/Si and N/Al ratios together with Ar etching revealed vealed a heterogeneous chemical composition in sub-nanometric dimensions. Furthera heterogeneous chemical composition in sub-nanometric dimensions. Additionally, the more, the observed reduce was greater for CL-HDTMA (39 ) than for CH-HDTMA observed reduce was larger for CL-HDTMA (39 ) than for CH-HDTMA (19 ), resulting (19 ), resulting from extra frequent (sandwich) organic double layers formed on flat surfrom extra frequent (sandwich) organic double layers formed on flat surface on the CLface with the CL-HDTMA. Figure 6c,d confirms Br presence around the double organic layer HDTMA. Figure 6c,d confirms Br presence on the double organic layer SMZs. For each SMZs. For each materials, Br 3d5/2 bond energies have been estimated at 67.four eV, which can be extremely components, Br 3d5/2 bond energies had been estimated at 67.4 eV, which can be incredibly close to pure close to pure HDTMA (66.9 eV). This supports the concept that a a part of HDTMA moleHDTMA (66.9 eV). This supports the notion that a part of HDTMA molecules is chemically cules is chemically unbounded using the zeolitic surfa.
