The D(r) functions of the composites and their corresponding physical mixtures have the same main correlations as their constituents (Figure .c), which confirms the structural integrity of both the Ti-MOF and IG component materials (Figure ). The peak areas vary, depending on the proportion of Ti-MOF and glass in the composite. C-H and Ti-O correlations located at 0.9, 1.98 (B1), 2.1 Å (B2), respectively, are related to the Ti-MOF. P-O (1.53 Å, the majority component of the peak at this distance) and P•••Na (3.46 Å) correlations increase in area when the proportion of the glass in the composite is higher. Other features related to atomic correlations from the Ti-MOF and the inorganic glass overlap, which makes their identification more complex.
