Pair Distribution Function (PDF) analysis confirmed the structural integrity of the phases. Total scattering data for the [(agZIF-UC-7)0.5(UiO-66)0.5] composite, physical mixture and its starting materials were collected and processed to produce structure factors, S(Q)s. The S(Q) of UiO-66 shows Bragg peaks (Fig. ) consistent with the crystal structure of UiO-66. The S(Q) of agZIF-UC-7, as expected, does not contain Bragg features because of the amorphous structure of the glass. The S(Q) of the [(UiO-66)0.5(agZIF-UC-7)0.5] composite retained UiO-66 Bragg features, indicating its preservation during the composite synthesis. Additionally, the S(Q)s of the [(UiO-66)0.5(agZIF-UC-7)0.5] composite and (agZIF-UC-7)(UiO-66)(50/50) physical mixture are largely similar, suggesting no decomposition or recrystallisation of the starting materials after composite fabrication (Fig. ). Fourier transforming the S(Q)s produced the real-space PDFs. In this work we use the D(r) function to highlight the medium-long r-range correlations. The D(r)s of the pristine materials exhibited expected correlations according to literature (Fig. ). As with the S(Q)s, the D(r)s of the [(UiO-66)0.5(agZIF-UC-7)0.5] composite and (UiO-66)(agZIF-UC-7)(50/50) mixture were nearly identical (Fig. ). The D(r) of the composite shows short-range correlations from both starting materials (Fig. .b) (See Supplementary information for assignment of starting materials' D(r)s), with peak intensities between those of the agZIF-UC-7 and UiO-66 starting materials). Correlations above ~8 Å arise from long-range order of the crystalline UiO-66 phase. The PDF results show that both phases were maintained after composite formation. Thermal stability was evaluated by TGA (Fig. ), which shows Tds of 411 °C and 425 °C for the physical mixture and composite respectively. DSC analysis on the physical mixture and composite show a peak at ~100 °C in the first DSC upscan, corresponding to water evaporation, which is also present in the first DSC upscan of UiO-66 (Fig. ). The agZIF-UC-7 Tg (~273 °C) is present in both DSC upscans of the physical mixture and [(UiO-66)0.5(agZIF-UC-7)0.5], indicating structural preservation of the agZIF-UC-7.
