PXRD patterns of pristine and water-treated (a) AEPz-SnS-1 and (b) trenH-SnS-1. The positions of the (100) and (002) peaks of the pristine samples are shown. The peak at 0.86 Å−1 corresponds to (102). The calculated patterns are based on the crystal structure of trenH-SnS-1 (Filsø et al., 2017). Peaks from a minor SnO2 impurity are observed at 1.88 and 2.38 Å−1 in the 20 and 60 min trenH-SnS-1 samples. The same batch of trenH-SnS-1 was used for preparation of all samples presented in Figs. 2(b) and 2(d), and the SnO2 peaks are barely observable except for samples with low thiostannate crystallinity, i.e. 20 and 60 min trenH-SnS-1 (see Figs. S1b and S6). PDFs of pristine and water-treated (c) AEPz-SnS-1 and (d) trenH-SnS-1. |
