Fig. 3

a Cryo-SEM images and b cryo-TEM images of Mo7–Fe hydrogel with a Mo7/Fe3+ molar ratio of 1:10, indicating the formation of branched structures in the Mo7–Fe gel networks. c SAXS spectra monitoring the gelation process with different molar ratios of Mo7/Fe3+. The arrows are used to connect the SAXS spectra with corresponding phases. d In situ optical microscopy of the aggregates formed by Mo7 and Fe3+ in aqueous solution.
